Subject: iwlwifi: pcie: prefer to load the firmware in one shot

Users complained about allocation failures, so we loaded
the firmware in small chunks (PAGE_SIZE). This makes the
firmware restart considerably slower.
So, always prefer to load it in one shot allocating a big
chunk of coherent, and use smaller chunks as a fallback
solution.

On my laptop, this reduces the fw loading time from 120ms
to 20ms.

Subject: iwlwifi: mvm: Loosen the channel context/phy context coupling

In current implementation, the phy context is tightly coupled
with the channel context. This complicates the possibility of
using the same phy context for both netdev interfaces and the P2P
Device interface. To loosen this coupling:

1. Manage all the phy contexts in the mvm op mode, and only save
   the phy context id in the chanctx memory.
2. Reference count the phy contexts and free them only when they
   are not longer used (both by mac80211 and P2P Device).

Subject: iwlwifi: mvm: Change PHY context handling

1. All the phy contexts are added immediately after the
   firmware is loaded and up.
2. Whenever a PHY context needs to be used, its reference
   counter is incremented and the PHY context is being
   configured to the appropriate configuration.
3. When a PHY context is no longer needed, its reference
   count is decremented.
4. PHY contexts are never removed.

Subject: iwlwifi: enable shadow registers for 7000

This will reduce CPU utilization. Instead of waking up the
NIC for each Tx manually, the CPU can write to a register
that will wake up the NIC automatically.

Subject: iwlwifi: mvm: don't assume data section is at 0x800000

In theory, the firmware format allows changing the data section
offset. This may not be used today, but there's no reason for
the driver to assume the data section is always at 0x800000 as
it can know better.

Subject: iwlwifi: pcie: dump stack on NIC error in sync commands

Many times, a NIC error is the result of a bad command sent
to the device. If the command was sent synchronously, then
we'll currently print a message when the command is aborted
containing the command. It can be very useful to also see
the stack dump though, so also print that.

Some devices don't support VHT (802.11ac) and this is encoded
in the data stored in the NVM. Read the flag and use it to set
up the VHT capabilities accordingly.

Subject: iwlwifi: mvm: Allow P2P Device to use an existing PHY context

The patch is an optimization, that eliminates unnecessary binding
context switching and allows the P2P Device MAC to use the same channel
as an existing netdev interface.

For each ROC call, check if there is already a channel/phy context that
can be used for the P2P Device. If such channel is found, unbind
the P2P Device from its current phy context, and bind it to the already
used channel/phy context. In case that the phy context is shared,
and there is a need to change it, create a new phy context, unbind and
create a new binding.

Subject: iwlwifi: mvm: optionally store D3 SRAM after resume

The D3 image SRAM is overwritten by the runtime image, so
it can't be accessed after resume. However, it can be very
useful to look at it to know what happened during D3, so
add the ability to store the image and make it available
in debugfs.

As the new MVM firmware files package the DATA section
first, and debugfs files want to access the DATA and
not INST section, reverse the order here. This is only
relevant for debugfs code that accesses the SRAM DATA
section and uses this constant to access the section.

Subject: iwlwifi: support loading NVM data from file

Some newer devices will be integrated into the platform more
deeply and will not have embedded NVM (EEPROM/OTP). To support
such devices the NVM data must be provided by the platform,
allow loading the data via request_firmware() and then send it
to the device as needed.

Subject: iwlwifi: fix initialisation while RF-kill is asserted

If RF-kill is asserted while a device is initialized, the
firmware INIT image can now be run to retrieve the NVM
data and register to mac80211 properly. Previously, the
initialisation would fail in this scenario and the driver
wouldn't register with mac80211 at all, making the device
unusable.

Subject: iwlwifi: mvm: don't store section offset/length in debugfs

When different images can (soon) be accessed through this
file, storing the section offset/length on first access to
the file breaks (or needs manual reset). Avoid this by not
storing the offset/length values but using them locally in
the function only. That way, the correct values are always
used.

While at it, correct the check that firmware is loaded.

Subject: vxlan: listen on multiple ports

The commit 823aa873bc782f1c51b1ce8ec6da7cfcaf93836e
  Author: stephen hemminger <stephen@networkplumber.org>
  Date:   Sat Apr 27 11:31:57 2013 +0000

    vxlan: allow choosing destination port per vxlan

introduced per-vxlan UDP port configuration but only did half of the
necessary work.  It added per vxlan destination for sending, but
overlooked the handling of multiple ports for incoming traffic.

This patch changes the listening port management to handle multiple
incoming UDP ports. The earlier per-namespace structure is now a hash
list per namespace.

It is also now possible to define the same virtual network id
but with different UDP port values which can be useful for migration.

Subject: xen-netback: remove dead code

The array mmap_pages is never touched in the initialization function. This is
remnant of mapping mechanism, which does not exist upstream. In current
upstream code this array only tracks usage of pages inside netback. Those
pages are allocated when contructing a SKB and passed directly to network
subsystem.

Subject: xen-netback: enable user to unload netback module
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch enables user to unload netback module, which is useful when user
wants to upgrade to a newer netback module without rebooting the host.

Netfront cannot handle netback removal event. As we cannot fix all possible
frontends we add module get / put along with vif get / put to avoid
mis-unloading of netback. To unload netback module, user needs to shutdown all
VMs or migrate them to another host or unplug all vifs before hand.

Subject: tg3: Add tg3_eee_pull_config() function

Add tg3_eee_pull_config() to pull the settings from the hardware and
populate the eee structure.

If Link Flap Avoidance is enabled, we pull the eee settings from the hw
so as not to cause a phy reset on eee config mismatch later. This
requires moving down tg3_setup_eee() below the tg3_pull_config() to not
trample existing settings.

Subject: tg3: Simplify tg3_phy_eee_config_ok() by reusing
 tg3_eee_pull_config()

eee_config_ok() was checking only for mismatch in advertised settings.
This patch expands the scope of eee_config_ok() to check for mismatch in
the other eee settings. On mismatch we will require a call to
tg3_setup_eee() to push the configured settings to the hardware.

Subject: net-bnx2x: dont reload on GRO change

bnx2x_set_features() forces a driver reload if GRO setting is changed.

A reload makes the ethernet port unresponsive for about 5 seconds.

This is not needed in the common case LRO is enabled, as LRO
(TPA_ENABLE_FLAG) has precedence over GRO (GRO_ENABLE_FLAG)

Tested:
 Verified that "ethtool -K eth0 gro {on|off}" doesn't blackout
 the NIC anymore

From e2c41f143fb2db14ad9b644a515c98e6c2e5ea2d Mon Sep 17 00:00:00 2001
From: Tony Prisk <linux@prisktech.co.nz>
Date: Sat, 18 May 2013 09:39:06 +0000
Subject: net: velocity: Convert to generic dma functions

Remove the pci_* dma functions and replace with the more generic
versions.

In preparation of adding platform support, a new struct device *dev
is added to struct velocity_info which can be used by both the pci
and platform code.

+* VIA Velocity 10/100/1000 Network Controller
+
+Required properties:
+- compatible : Should be "via,velocity-vt6110"
+- reg : Address and length of the io space
+- interrupts : Should contain the controller interrupt line
+
+Optional properties:
+- no-eeprom : PCI network cards use an external EEPROM to store data. Embedded
+	devices quite often set this data in uboot and do not provide an eeprom.
+	Specify this option if you have no external eeprom.
+
+Examples:
+
+eth0@d8004000 {
+	compatible = "via,velocity-vt6110";
+	reg = <0xd8004000 0x400>;
+	interrupts = <10>;

Subject: fec: Let device core handle pinctrl

Since commit ab78029 (drivers/pinctrl: grab default handles from device core)
we can rely on device core for handling pinctrl, so remove
devm_pinctrl_get_select_default() from the driver.

Subject: bna: Clear Driver Config Flags When HW Resets

Driver configuration flags are retained across open/stop operations preventing
configurations to be set in next open/stop. Setting MTU on a 1020 causes
network to fail until a reboot is performed on the host.

Clear the flags when configuration resets in hardware.

Subject: bna: Fix Ucast Failure Handling

Failure of the UCAST set for base mac address fails when user configures a
duplicate mac address that matches that of another vNIC on the same port.
The bna does not handle the ucast failure and keeps this address in cache.
On disable of the vNIC, bna tries to delete the failed base mac address and the
fw asserts.

On failure of ucast address, mark ucast address set to false.

Subject: phy: fix the use of PHY_IGNORE_INTERRUPT

When a PHY device is registered with the special IRQ value
PHY_IGNORE_INTERRUPT (-2) it will not properly be handled by the PHY
library:

- it continues to poll its register, while we do not want this
  because such PHY link events or register changes are serviced by an
  Ethernet MAC
- it will still try to configure PHY interrupts at the PHY level, such
  interrupts do not exist at the PHY but at the MAC level
- the state machine only handles PHY_POLL, but should also handle
  PHY_IGNORE_INTERRUPT similarly

This patch updates the PHY state machine and initialization paths to
account for the specific PHY_IGNORE_INTERRUPT. Based on an earlier patch
by Thomas Petazzoni, and reworked to add the missing bits. Add a helper
phy_interrupt_is_valid() which specifically tests for a PHY interrupt
not to be PHY_POLL or PHY_IGNORE_INTERRUPT and use it throughout the
code.

Subject: phy: add phy_mac_interrupt() to use with PHY_IGNORE_INTERRUPT

There is currently no way for an Ethernet MAC driver servicing PHY link
interrupts to notify this to the PHY state machine without defining its
own state machine. Since most drivers are not so special, introduce a
helper: phy_mac_interrupt() which can be called from a link up/down
interrupt routine to update the PHY state machine. To avoid code
duplication some refactoring has been done to expose the workqueue and
its corresponding callback internally.

Subject: e1000e: Release mutex lock only if it has been initially acquired

This patch fixes the issue of unlocking swflag_mutex for 82574 and 82583
devices regardless of if the hw semaphore has been successfully acquired via
e1000_get_hw_semaphore_82574(). With this patch, unlocking mutex now depends
on if the hw semaphore was successfully acquired before. And 82574/82583
devices are reset regardless of whether e1000_get_hw_semaphore_82574()
returns success or failure.

Subject: igb: Changed LEDs blink mechanism to include designs using cathode

This patch addresses the changes needed to make LEDs work properly with
negative logic. This implementation uses LED Invert bit to reverse the
logic issue that occurred when LEDs are driven by cathode. Keep LEDs
blinking for SerDes devices. Also made changes to magic number and the
for loop to reduce number of shifts.

Subject: igb: Add update to last_rx_timestamp in Rx rings

In order to support a more accurate check for a PTP Rx hang where the
device can no longer timestamp received packets, we need to update, per
ring, when the last Rx timestamp was. Because of how the PTP Rx hang logic
works, the current logic is valid, but properly updating the ring variable
increases the accuracy of the check.

Subject: igb: SerDes flow control setting

This path allows users to get appropriate flow control setting on SerDes
devices, based on original implementation for Copper devices.
Also, since 100baseFX does not support setting flow control, so exclude
it from the setting mechanism.

Set the SW prio_tc values at initialization to the HW setting.
Setting the SW prio_tc default values to be the HW setting by reading the
rtrup2tc register. For any TC change we need to reset the device.
This will remove the need to reset the device at the first
time we call ixgbe_dcbnl_ieee_setets.

Subject: rt2x00: rt2800pci: use rt2x00dev->tx->limit

The TX data queue is initialized already when
the rt2800pci_txstatus_interrupt() function is
called.

Fetch the number of the queue entries from that
instead of using the entry_num field of the data
queue descriptor.

The two values are the same, and the use of the
rt2x00dev->tx->limit value allows us to get rid
of a superfluous pointer dereference.

Subject: ath9k: Remove MAC_DEBUG

This option has not been enabled by default in any
distribution, has never been enabled in OpenWrt and no developer
has asked for this information in a bug report.

Dumping pages of random values doesn't help debugging,
remove this option (along with the vmalloc() abuse).

Subject: ath9k: Do not use local_bh_disable in ampdu_action

This was added during the early conversion of ampdu_action
to a sleeping callback. There is no need to do this - instead,
use the normal mutex that is acquired for all callbacks.

support.

Coexistence with a virtual STA interface was tested as
working fine.

Subject: ath9k: use ap style beaconing for mesh

Chun-Yeow and Javier Lopez contributed these changes to
make mesh mode use the more similar AP beaconing mode and
queue parameters. Should improve PS performance, interface
concurrency (AP modes can coexist), and beacon interval
stability.

AR9271 (ath9k_htc) mesh interfaces also need to be in AP
operating mode.

Subject: wil6210: Sanity check for reported DMA length

If Rx descriptor contains garbage, it is possible to access memory beyond
allocated buffer.

Check this condition and drop Rx if reported length is
unreasonable large

From e0287c4ab87905dd4a2e45cf791f8e0a87fe602e Mon Sep 17 00:00:00 2001
From: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com>
Date: Sun, 12 May 2013 14:43:36 +0300
Subject: wil6210: use NAPI

Introduce NAPI for Rx and Tx completion.

This fixes packet reordering that happens when Rx handled right in
the IRQ: netif_rx puts packet in 'percpu' queue, then network stack
fetches packets from 'percpu' queues for processing, with different
pattern of queue switching. As result, network stack see packets
in different order. This causes hard to understand TCP throughput
degradation in about 30min

Complete polling if only one packet was processed - this eliminates
empty polls that would be otherwise done at the end of each burst

Subject: wil6210: fix remaining use of non-cached copy of tx/rx descriptors

- Introduce common code for Tx/Rx descriptor physical address set/parse
- Fix endianness for address fields
- consistent descriptor naming: '_d' for non-cached memory, 'd' for cached copy
- wil_tx_desc_map now modify cached copy, no need for 'volatile'

Subject: wil6210: do not stop Tx queue on packet drop

Packet drop may be caused by various flows, like disconnect
while Tx packets was queued; this should not lead to stopping
of the Tx queue, or all Tx get stalled.

Subject: mwifiex: rename mwifiex_free_adapter() routine in init.c

We have two different static routines with name
mwifiex_free_adapter(). The routine in main.c actually frees the
adapter structure.

We will rename other routine in init.c to mwifiex_adapter_cleanup()
to avoid confusion.

Subject: mwifiex: scan delay timer cleanup in unload path

Return from scan delay timer routine if surprise_removed flag
is true. Also, cancel the timer in unload path.

This fixes a crash when scan delay timer accesses structures
that have been freed already.

Tested with "iwlist mlan0 scan & sleep 1; rmmod mwifiex_sdio"

Subject: mwifiex: remove global user_scan_cfg variable

As the variable is used only for preparation of internal scan
commands, we don't need to keep it allocated until the entire
scan completes. We will define it as a local variable and free
immediately after it's use.

New flag 'scan_aborting' is added to handle race between
mwifiex_close() and scan handler. Previously user_scan_cfg
pointer used to take care of this.

This patch fixes a memory leak in mwifiex_cfg80211_scan after
running "iwlist mlan0 scan & sleep 1; rmmod mwifiex_sdio".

Subject: mwifiex: abort remaining scan commands when association started

A full-channel scan is split to multiple scan commands in driver
before they are sent to firmware. When each scan result is back
the SSID entries are parsed and informed to cfg80211 directly.

It's observed that sometimes userspace may initiate association
as soon as the target AP is found. During the 4-way handshake
firmware may go off-channel to scan the remaining channels.
This causes the 4-way handshake to fail.

Fix it by checking 'scan_block' flag and aborting the remaining
scan in this case. 'scan_block' flag is set after association
and before 4-way handshake. It gets cleared after 4-way handshake
is completed.

During deleting a station entry from associated sta_list, we are
supposed to delete entry only for this particular mac address.
This patch is a bug fix wherein we were deleting all entries from
list; fix this by removing list_for_each_entry_safe() call.

Subject: mwifiex: replace spin_lock_irqsave with spin_lock and fix warn_on

We see this WARN_ON during PCIe unload:
WARNING: at kernel/smp.c:382 smp_call_function_many+0x66/0x1e1()

This happens because we are doing PCI iounmap operations while
holding spinlock via spin_lock_irqsave(). Holding spinlock this
way causes disabling IRQs and hence PCI iounmap shows warning on
irqs_disabled() check.

Use non-irq variant of spin_lock i.e. spin_lock() instead.

Subject: mwifiex: code rearrangement in multiport aggregation path

There are some macros defined for multiport aggregation
calculations. As we may need to add some more code to
accomodate new chipsets, we will change them to inline
functions. Also, use dynamic allocation for Rx buffer array.

From b60186f824330cd85859f5944b9559b0f7df0b4f Mon Sep 17 00:00:00 2001
From: Yogesh Ashok Powar <yogeshp@marvell.com>
Date: Fri, 17 May 2013 17:54:58 -0700
Subject: mwifiex: add support for Marvell SD8897 chipset

Some of the key differences between SD8897 and older chipsets
are as follows:

a) sdio mpa_rx and mpa_tx ports have been increased from 16 to 32
b) Same is the case with read/write bitmap that one receives from
   mpa_reg read
c) aggregation packet count doubled from 8 to 16
d) Most of key reg addresses are changed
e) There is a separate command or control port
f) Now command rx/tx_done have new interrupts

1. 'supports_sdio_new_mode' flag is added to handle (a) and (b).
2. (c) and (d) are taken care of by filling chip specific
   information in global structurei (mwifiex_sdio_sd8897).
3. For older chipsets, port 0 was cmd port and port 1->15 were
   data port. Therefore we had CTRL_PORT_MASK to differentiate
   port type. Now these changes are under 'has_control_mask' flag.

Date: Tue, 21 May 2013 00:22:37 +0000
Subject: net: smsc911x: don't artificially limit build

Currently the SMSC911X driver may only be built for a specific set of
architectures, being limited to do so by a Kconfig depends line. This
means that if a platform wishes to use the driver, its architecture must
be added to the list explicitly, introducing pointless churn.

This may have been due to the driver's use of the {read,write}s{b,w,l}
functions, which have since been replaced with the more standard
io{read,write}{8,16,32}_rep. We can instead depend on HAS_IOMEM, which
should prevent build issues while allowing the driver to be built for
currently unlisted architectures, including x86 and arm64.

This patch removes the explicit list of architectures from the driver's
depend line, and replaces it with a dependency on HAS_IOMEM.

Unfortunately, advertising P2P_DEVICE support was a little
premature, a number of issues came up in testing and have
been fixed for 3.10. Rather than try to backport all the
different fixes, disable P2P_DEVICE support in the drivers
using it. For iwlmvm that implies disabling P2P completely
as it can't support P2P operation w/o P2P Device.

Subject: xen-netback: split event channels support for Xen backend driver

Netback and netfront only use one event channel to do TX / RX notification,
which may cause unnecessary wake-up of processing routines. This patch adds a
new feature called feature-split-event-channels to netback, enabling it to
handle TX and RX events separately.

Netback will use tx_irq to notify guest for TX completion, rx_irq for RX
notification.

If frontend doesn't support this feature, tx_irq equals to rx_irq.

From d634bf2cb96639b7eddb646dc1fc17b1bc6e567f Mon Sep 17 00:00:00 2001

Subject: xen-netfront: split event channels support for Xen frontend driver

This patch adds a new feature called feature-split-event-channels for
netfront, enabling it to handle TX and RX events separately.

If netback does not support this feature, it falls back to use single event
channel.

If netfront fails to setup split event channels, it will try falling back to
single event channel.

Subject: bnx2x: Link-flap avoidance in switch dependent mode

As part of the previous unload flow, probed devices will reset the chip
in order to clean the remains of the UNDI driver.
As a result, it's possible for the FW to toggle the link.

This toggling can prove fatal, as long periods without link can cause the
filesystem mount to fail as the storage protocol timeouts. This has been
observed against particular switches with long link re-establishment time.

This patch informs FW during the reset period that the link should not
be toggled - the FW will keep it alive until some interface will load and claim
the link as its own.

Subject: bnx2x: Wait for MCP validity during AER

During PCIe advanced error recovery, the secondary bus reset will cause FW
to reset; This will cause the shared memory between it and the driver to be
invalidated.

During the driver's recovery flow, the driver should not make any assumption
on the validity of that memory and instead re-initialize it.

This also removes a redundant re-initialization of a previously
initialized mutex.

Subject: mwl8k: Fix the firmware hang issue for 8764

The firmware hang issue is not seen very often,
though it is still seen sometimes (once in 12
hours in local tests). The changes in the driver
,to interrupt the firmware, are needed when we
detect that firmware is stuck and when the host
queues are full and we begin to drop packets.
This is to ensure that the firmware does not
miss any PPA_RDY interrupts to cause the firmware
restart dont miss PPA_READY interrupt for SC2

Subject: tg3: Split APE driver state change out of boot reset signature update

Unlike the boot signature that needs to be set before every reset, the
ape state only needs to be updated to tell the firmware that the driver
is now taking/releasing control of the hardware. Move the calls to
tg3_ape_driver_state_change() to better, more appropriate places.

Also, the firmware does not distinguish between SUSPEND and START states
anymore. Remove the SUSPEND case in the switch.

Subject: tg3: Remove unnecessary lock around tg3_flag_set

The spinlock was needed when flags used to be a u32 and set/cleared
using bit operations. Now that we use the atomic set_bit, this lock
isn't needed.

Subject: qlcnic: Implement GET_LED_STATUS command for 82xx adapter.

o GET_LED_STATUS command will be used by driver to get
  current beacon state from 82xx adapter.
o Refactored qlcnic_store_beacon() to split 8200 and 8300
  specific calls.

Subject: net: ethernet: use platform_{get,set}_drvdata()

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Subject: iwlwifi: move D3_CFG_COMPLETE handling into DVM

The MVM firmware doesn't communicate this way, it instead
assumes D3 configuration is complete after a specific host
command (which must be last) has been sent. Handling this
bit thus belongs into the firmware API code, i.e. DVM.

Subject: iwlwifi: dvm: rename iwl_lib_ops to iwl_dvm_cfg

The next patches will move some more configuration
data that isn't needed by mvm into this struct, so
rename it now since it won't just be ops.

Subject: iwlwifi: move some configuration parameters into DVM

There are a number of parameters that aren't really hardware
specific but rather define how the DVM firmware is used.
Move these into the DVM configuration.

a message unknown to the PF (e.g. VF with more advanced version).

Subject: bnx2x: Count number of possible FCoE interfaces

Commit 0eb43b4bb081a1a22574daab9c05286a600dd7fe
"bnx2x, bnx2fc: Use per port max exchange resources" has changed the number
of available FCoE exchanges, even in scenarios when some of the functions has
no FCoE support; This needlessly degraded the available resources.

Remedy this by calculating the maximal number of functions that may actually
utilize said connection.

Subject: bnx2x: Implement PCI shutdown

Implement the PCI shutdown callback to support un-orderly shutdown, i.e.,
shutdowns in which the remove callback will not be called.

Due to the lack of this functionality, when an un-orderly shutdown occurred,
it was possible for wake-on-lan to remain disabled.

This is now fixed as the callback introduces the correct place in which
`system_state' can be queried and wake-on-lan be configured accordingly.

Date: Mon, 27 May 2013 04:08:31 +0000
Subject: bnx2x: Change to D3hot only on removal

This changes the PCI power management scheme of the bnx2x driver to be similar
to those of most network drivers - the driver will now changes the power state
into D3hot whenever the driver will be removed, instead of whenever an
interface is unloaded.

This change enables the driver to access its eeprom via ethtool callbacks
even when interfaces are unloaded (such access requires the function to be
in D0active).

Instead of using a local reg_phy structure, let's put it inside the private

when we are outside fec_probe().

This is in preparation for controlling the FEC PHY regulator in the suspend and
resume functions.

Subject: fec: Invert the order of error path sequence

Currently when fec_enet_init fails it jumps to 'failed_init' error path, which
will attemp to free the interrupts.

This is wrong because at this point the interrupts have not even been acquired.

Swap failed_init/failed_irq to fix the error path.

Subject: fec: Disable the PHY regulator on error and removal

In the case of error during probe, disable the PHY regulator.

Do the same in fec_drv_remove().

Subject: fec: Remove irqs first

During probe the clocks are enabled prior than the acquiring the interrupts.

In the remove function we need to do the opposite: first remove the interrupts
and then disable the clocks.

In order to save power, let's disable the regulator in the suspend function and
enable it in resume.

Tested on a mx28evk board.

Subject: net: ethernet: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

Subject: net: irda: remove unnecessary platform_set_drvdata()

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

Subject: phy: allow drivers to flag a PHY device as internal

libphy currently always reports a PHY as an external transceiver from
the ethtool output. This is inaccurate, because some drivers should be
able to tell that a PHY device is an internal transceiver of an Ethernet
MAC. Add a new flag (PHY_IS_INTERNAL) which can be set by PHY drivers
just like other flags, and a corresponding helper: phy_is_internal()
which can be used by networking drivers to query if a given
PHY device is internal.

Subject: bonding: allow xmit hash policy change while bond dev is up

Since the xmit_hash_policy pointer is always valid and not dependent on
anything, we can change it while the bond device is up and running. The
only downside would be the out of order packets but that is a small price
to pay.

Subject: isdn: Correct comparison of skb->tail and skb-transport_header

This corrects an regression introduced by "net: Use 16bits for *_headers
fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In
that case skb->tail will be a pointer whereas skb->transport_header
will be an offset from head. This is corrected by using wrappers that
ensure that the comparison is always between pointers.

Subject: vxlan: defer vxlan init as late as possible

When vxlan is compiled as builtin, its init code
runs before IPv6 init, this could cause problems
if we create IPv6 socket in the latter patch.

Subject: iwlwifi: mvm: add thermal throttling and CT kill

In order to avoid NIC destruction due to high temperature,
CT kill will power down the NIC.

To avoid this, thermal throttling will decrease throughput
to prevent the NIC from reaching the temperature at which
CT kill is performed.

Subject: iwlwifi: mvm: Change number of DTIMs to skip semantics

If skip over DTIMs is enabled the driver can specify number of DTIMs
to skip. This parameter in host-device API implies number of DTIM
periods to skip. For example, to skip one DTIM means sleep over two

Subject: iwlwifi: mvm: Add support for connection monitor offload

The firmware supports periodic keep alive and beacon monitoring,
so advertise connection monitor offload capability by setting
IEEE80211_HW_CONNECTION_MONITOR flag. Implement missed beacons
notification handler. Call ieee80211_beacon_loss in case of
missed beacons, so AP probing by mac80211 can be triggered.

Subject: ath9k_hw: fix PA predistortion miscalibration

If any bins from the training data are skipped (i != max_index), the
calculated compensation curve gets distorted, and the signal will be
wildly overamplified. This may be the cause of the reported hardware
damage that was caused by PA predistortion (because of which PAPRD was
disabled by default).

When calculating the x_est, Y, theta values, the use of max_index and i
was reversed. i points to the bin index whereas max_index refers to the
index of the calculated arrays.

Note that PA predistortion is still disabled, it will be re-enabled
after it has been properly validated.

From debff6184c32149bd08cfecfafbebb96201be37d Mon Sep 17 00:00:00 2001

Subject: iwlwifi: mvm: implement D3 testing

For testing the D3 (WoWLAN) firmware, it is useful to be able
to run the firmware with instrumentation while the host isn't
sleeping and can poke at the firmware debug logging etc.

Implement this by a debugfs file. When the file is opened the
D3 firmware is loaded and all regular commands are blocked.
While the file is being read, poll the firmware's PME status
flag and report EOF once it changes to non-zero. When it is
closed, do (most of) the resume processing. This lets a user
just "cat" the file. Pressing Ctrl-C to kill the cat process
will resume the firwmare as though the platform resumed for
non-wireless reason and when the firmware wants to wake up
reading from the file automatically completes.

Unlike in real suspend, only disable interrupts and don't
reset the TX/RX hardware while in the test mode. This is a
workaround for some interrupt problems that happen only when
the PCIe link isn't fully reset (presumably by changing the
PCI config space registers which the core PCI code does.)

Note that while regular operations are blocked from sending
commands to the firmware, they could still be made and cause
strange mac80211 issues. Therefore, while using this testing
feature you need to be careful to not try to disconnect, roam
or similar, and will see warnings for such attempts.

Als note that this requires an upcoming firmware change to
tell the driver the location of the PME status flag in SRAM.
D3 test will fail if the firmware doesn't report the pointer.

Subject: ath9k: remove useless flag conversation.

some flags used only outside of ath9k - In this case we can use
"enum mac80211_rx_flags" and pass it upstream without extra
conversation.

Subject: ath9k: check for Rx-STBC flag and pass it to ieee80211

This patch make use of STBC flag in DMA RX descriptor.
Only devices after ar9280 can provide this information.

If card support it we will set HAVE_STBC flag, to show
clint programm thet STBC is supported but not received.

Subject: net: mv643xx_eth: use phy_disconnect instead of phy_detach

Using a separated mdio bus driver with mvmdio, phy_detach on network device
removal will not stop the phy and finally lead to NULL pointer dereference
in mvmdio due to non-existent network device. Use phy_disconnect instead
to properly stop phy device from accessing network device prior removal of
the network device.

Subject: net: mv643xx_eth: proper initialization for Kirkwood SoCs

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.

This adds device tree parsing support for the shared driver of mv643xx_eth.
As the bindings are slightly different from current PPC bindings new binding
documentation is also added. Following PPC-style device setup, the shared
driver now also adds port platform_devices and sets up port platform_data.

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be one of "marvell,orion-eth-port",
+      "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+	...
+	ethphy: ethernet-phy@8 {
+		device_type = "ethernet-phy";
+		...
+	};
+};
+
+eth: ethernet-controller@72000 {
+	compatible = "marvell,orion-eth";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0x72000 0x2000>;
+	clocks = <&gate_clk 2>;
+	marvell,tx-checksum-limit = <1600>;
+
+	ethernet@0 {
+		device_type = "network";
+		compatible = "marvell,orion-eth-port";
+		reg = <0>;
+		interrupts = <29>;
+		phy-handle = <&ethphy>;
+		local-mac-address = [00 00 00 00 00 00];

Subject: Revert "iwlwifi: mvm: remove P2P_DEVICE support"

This reverts commit eebfc9394ee31b3ef162692c0cd483c1318a4395.

This wasn't intended to be included here, my mistake. I
accidentally merged a mac80211 fixes tree here that had
this change, when it wasn't even intended to be there.

The PHY library currently does not know about the the reverse MII
connection type. Add it to the list of supported PHY modes and update
of_get_phy_mode() to support it and look for the string "rev-mii".

Subject: net: Add EMAC ethernet driver found on Allwinner A10 SoC's

The Allwinner A10 has an ethernet controller that seem to be developped
internally by them.

The exact feature set of this controller is unknown, since there is no
public documentation for this IP, and this driver is mostly the one
published by Allwinner that has been heavily cleaned up.

+* Allwinner A10 MDIO Ethernet Controller interface

+Required properties:
+- compatible: should be "allwinner,sun4i-mdio".
+- reg: address and length of the register set for the device.
+
+Optional properties:
+- phy-supply: phandle to a regulator if the PHY needs one
+
+Example at the SoC level:
+mdio@01c0b080 {
+	compatible = "allwinner,sun4i-mdio";
+	reg = <0x01c0b080 0x14>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+};
+
+And at the board level:
+
+mdio@01c0b080 {
+	phy-supply = <&reg_emac_3v3>;
+
+	phy0: ethernet-phy@0 {
+		reg = <0>;
+	};

Subject: drivers: net: davinci_cpdma: remove CRC bytes from skb added by CPDMA

Additional 4 bytes found in the skb is the CRC calculated by the
CPDMA hardware, check the CRC bit in CPDMA status field of
Descriptor and remove the CRC length from the skb. This extra
4 byte can be seen when capturing packets using tcpdump.
This has been tested in TI816x platform.

Subject: cxgb4: Force uninitialized state if FW_ON_ADAPTER is < FW_VERSION and
 we're the MASTER_PF

Forcing uninitialized state allows us to upgrade and reinitialize the adapter.

FW_VERSION_T4 = 1.4.0.0
FW_VERSION_T5 = 0.0.0.0
At this point driver supports above and greater than above version of firmware.
If it doesn't find the required firmware version than it forces the adapter to
be reinitialized as shown below.

1) If FW_ON_ADAPTER < FW_VERSION and we're the MASTER_PF force uninitialized
   state and a FW upgrade if available.

       - If FW_ON_ADAPTER < /lib/firmware/cxgb4/t*fw.bin we will update the
         adapters FW.
       - If FW_ON_ADAPTER >= /lib/firmware/cxgb4/t*fw.bin don't upgrade FW.
       - If upgrade_fw() fails force reinitialization of the adapter anyways,
         it might still work.

   Either way forcing the uninitialized state allows cxgb4 reinitialize FW.

2) If FW_ON_ADAPTER >= FW_VERSION driver follows normal path.

Subject: ath6kl: Check wmi ready event status before validating abi version

There is no point to check firmware ABI version when the driver
fails to wait for WMI_READY event during the boot time.

For such failures, the driver should assume the firmware is not
booted and start doing cleanup.

Subject: ath6kl: Rename USB driver's suspend/resume/reset_resume

Rename USB driver's suspend/resume/reset_resume callbacks
with 'pm' prefix. This is necessary to differentiate it from
cfg80211/hif suspend/resume/reset_resume callbacks.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

sg_sz and buf_sz are initialized and used in a mutual exclusive way.
However, some versions of gcc are not smart enough to see this:

drivers/net/wireless/ath/ath6kl/sdio.c: In function ‘ath6kl_sdio_alloc_prep_scat_req’:
drivers/net/wireless/ath/ath6kl/sdio.c:338: warning: ‘sg_sz’ may be used uninitialized in this function

Unify the sg_sz and buf_sz variables into a single size variable to kill
the compiler warning.

Subject: bnx2x: use XPS if possible for bnx2x_select_queue instead of pure
 hash

The bnx2x_select_queue() was using __skb_tx_hash() to select the
transmit queue, totally ignoring XPS settings, while XPS can help
performance quite significantly, so change the bnx2x_select_queue()
to use __dev_pick_tx() instead which will use XPS if configured.

Based on patches from Ying Cai and Havard Skinnemoen

From 3cdeec22e40264e40d34d8242b4ce7461329a80a Mon Sep 17 00:00:00 2001
From: Yuval Mintz <yuvalmin@broadcom.com>
Date: Sun, 2 Jun 2013 00:06:19 +0000
Subject: bnx2x: Semantic removal and beautification

This patch introduces several small  changes to the driver, none which actually
change any flow:
 1. Removes prototypes of unexisting functions and unused defines.
 2. Fixes alignment and spacing issues.
 3. Changes numeric usage into constants.
 4. Remove unnecessary parenthesis.

From 639d65b85592cf31eca24f33ff00e309ebbf0d2b Mon Sep 17 00:00:00 2001
From: Yuval Mintz <yuvalmin@broadcom.com>
Date: Sun, 2 Jun 2013 00:06:21 +0000
Subject: bnx2x: semi-Semantic changes

This patch includes a few changes that change the driver's flow without truly
changing anything in its functionality - use usleep_range for short sleeps
instead of msleep and initialize Tx consumer during initialization for better
information during errors.

If PCIe supports PM capabilities, bnx2x will always claim eeprom is accessible
as PCI_D0 is zero.

Subject: ibm-ethernet: delete stale MCA and duplicate PSERIES dependency

MCA support has been removed but this dependency escaped removal.
Also, there is a duplicate PPC_PSERIES dependency that appeared
when the ethernet drivers were separated into vendor/model
specific directories, so we remove that here as well.

Subject: can: flexcan: Let device core handle pinctrl

Since commit ab78029 (drivers/pinctrl: grab default handles from device core)
we can rely on device core for handling pinctrl, so remove
devm_pinctrl_get_select_default() from the driver.

Subject: can: flexcan: remove HAVE_CAN_FLEXCAN Kconfig symbol

This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc}
and allowing compilation unconditionally on all arm and powerpc platforms.

This brings a bigger compile time coverage and removes the following dependency
warning found by Arnd Bergmann:

    warning: (SOC_IMX28 && SOC_IMX25 && SOC_IMX35 && IMX_HAVE_PLATFORM_FLEXCAN &&
        SOC_IMX53 && SOC_IMX6Q) selects HAVE_CAN_FLEXCAN
    which has unmet direct dependencies (NET && CAN && CAN_DEV)

Subject: net: can: use platform_{get,set}_drvdata()

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Subject: cfg80211: take WoWLAN support information out of wiphy struct

There's no need to take up the space for devices that don't
support WoWLAN, and most drivers can even make the support
data static const (except where it's modified at runtime.)

From 911373cca1b45571b62938f8f19cec24cb102471 Mon Sep 17 00:00:00 2001
From: Solomon Peachy <pizza@shaftnet.org>

Subject: cw1200: Rename 'sbus' to 'hwbus'

This avoids problems when building on SPARC targets due to the driver
calling the bus abstraction layer 'sbus'.  Not that any SBUS-sporting
SPARC targets are likely to have an SDIO controller, but this is the
correct thing to do.

See http://kisskb.ellerman.id.au/kisskb/buildresult/8846508/

Subject: cw1200: Replace use of 'struct resource' with 'int' for GPIO fields.

The only advantage of 'struct resource' is that it lets us assign names
as part of the platform data.  Unfortunately since we are using platform
data, we are already limited to a single instance of each driver,
rendering this moot.

So, replace the struct resources with ints, resulting in cleaner code.

This was based on a suggestion from Arnd Bergmann.

Subject: cw1200: Rework SDIO platform support to prevent build problems.

Based on discussions with And Bergmann, this patch changes the SDIO
platform code to default to supporting the Sagrad devices, allowing for
it to be overridden in board setup code.  This renders the cw1200_sagrad
module suplerflous, so it is now removed.

It also moves the documentation that was in the cw1200_sagrad source to
the platform header.

Subject: cw1200: rename the cw1200 platform definition header

My previous patch just moved the file, but it also needed to be renamed
to conform to proper conventions.

Pci_enable_device() will set device power state to D0,
so it's no need to do it again in ipw2100_pci_init_one().

Subject: ath9k: Enable WoW only for AR9462

The only card with which WoW has been tested and verified is
AR9462. Do not enable it for all cards since WoW is really quirky
and needs to be tested properly with each chip.

set to true and the logic for disabling/enabling ANI via
debugfs is done at a higher layer.

Subject: ath9k: Do not maintain ANI state per-channel

ANI state can be maintained globally instead of per-channel.
This reduces memory usage and since default values are used
during a scan run, per-channel state is not required.

Subject: iwlwifi: don't return -ERFKILL if SEND_IF_RFKILL is set

When CMD_SEND_IN_RFKILL is set, it is perfectly legitimate
to send a host command while RFKILL is asserted. In this
case, the host command sending functions should return 0
even if RFKILL is asserted.

Subject: iwlwifi: mvm: Fix quota command settings

According to the FW implementation, the quota command should
have a valid entry for each active binding (where 'active' in
this context means that the binding is known to the FW). In case
the binding should not get any quota, the 'quota' should be set
to zero.

Not setting an 0 quota for an active binding when all the MACs
in the binding are idle, i.e., not associated in case of managed
interface, will result in preventing the FW scheduler from entering
IDLE state and the FW from transitioning to low PS.

Subject: iwlwifi: mvm: correctly configure MCAST in AP mode

The AP mode needs to use the MCAST fifo for the MCAST
frames sent after the DTIM. This fifo needs to be
configured with the same parameters as the VOICE FIFO.

A separate SCD queue is mapped to this fifo - the cab_queue
(cab stands for Content After Beacon). This queue isn't
connected to any station, but rather to the MAC context.
This queue should (and is already) be set as the MCAST
queue - this is part of the of MAC context command.

Subject: drivers: net: phy: at803x: seperate wol specific code to wol standard
 apis

WOL is initilized in phy config_init, but there are standard apis
(set_wol/get_wol) for WOL in phy frame work. So this patch moves
WOL specific code from config_init to wol standard apis.

Subject: net: mv643xx_eth: add missing semicolon

76723bca28 "net: mv643xx_eth: add DT parsing support" added a
dummy mv643xx_eth_shared_of_probe() fallback function with a
typo.

This adds the missing semicolon so we can build without CONFIG_OF
again, and changes both dummy functions to the more conventional
"static inline" syntax, which can avoid potential problems with
the empty macro.

Subject: net: mvneta: read MAC address from hardware when available

This patch improves the logic used by the mvneta driver to find a MAC
address for a particular interface. Until now, it was only looking at
the Device Tree, and if no address was found, was falling back to
generating a random MAC address.

This patch adds the intermediate solution of reading the MAC address
from the hardware registers, in case it has been set by the
bootloader. So the order is now:

 1) MAC address from the Device Tree
 2) MAC address from the hardware registers
 3) Random MAC address

This requires moving the MAC address initialization a little bit later
in the ->probe() code, because it now requires the hardware registers
to be remapped.

Subject: net/mlx4: use one page fragment per incoming frame

mlx4 driver has a suboptimal memory allocation strategy for regular
MTU=1500 frames, as it uses two page fragments :

One of 512 bytes and one of 1024 bytes.

This makes GRO less effective, as each GSO packet contains 8 MSS instead
of 16 MSS.

Performance of a single TCP flow gains 25 % increase with the following
patch.

Before patch :

 mlx4_en_select_queue

mlx4_en_select_queue() uses __skb_tx_hash to select the transmit queue.
XPS settings are ignored by this. Instead, we can use __netdev_pick_tx
to select the transmit queue.

Compile test only.

Subject: net: sun4i-emac: remove erroneous assignment

The newly added sun4i-emac driver causes a build error when
CONFIG_NET_POLL_CONTROLLER is set, because it attempts to
assign a pointer to netdev->poll_controller, which has
been replaced with ops->ndo_poll_controller in 2.6.31!

The correct assignment is present as well, so we just need
to remove the wrong one.

Subject: cxgb3: Correct comparisons and calculations using skb->tail and
 skb-transport_header

This corrects an regression introduced by "net: Use 16bits for *_headers
fields of struct skbuff" when NET_SKBUFF_DATA_USES_OFFSET is not set. In
that case skb->tail will be a pointer whereas skb->transport_header
will be an offset from head. This is corrected by using wrappers that
ensure that comparisons and calculations are always made using pointers.

sets power management flag according to mac80211 decision. As result, in
unassociated mode power management flag is down and power consumption is
high. Change power management enablement. When unassociated in BPS and
LP power save modes enable power management regardless of mac80211
decision. Rely on mac80211 decision if associated. Add power management
state update during associated/disassociated modes transitions.

Subject: iwlwifi: mvm: fix MCAST in AP mode

In multicast, there is no retries nor RTS since there is no
specific recipient that can ACK or send CTS. This means
that we must not use the rate scale table for multicast
frames.
This true for any frame that doesn't have a valid
ieee80211_sta pointer.

Subject: mac80211: Use suitable semantics for beacon availability indication

Currently beacon availability upon association is marked by have_beacon
flag of assoc_data structure that becomes unavailable when association
completes. However beacon availability indication is required also after
association to inform a driver. Currently dtim_period parameter is used
for this purpose. Move have_beacon flag to another structure, persistant
throughout a interface's life cycle. Use suitable sematics for beacon
availability indication.

Remove SH_ETH_HAS_TSU #define's and #ifdef's. Set three 'struct net_device_ops'
methods that depend on the presence of TSU basing on the 'tsu' field of 'struct
sh_eth_cpu_data'.

Subject: sh_eth: add IRQ flags to 'struct sh_eth_cpu_data'

The driver supports some SH and SH-Mobile SOCs. There are SOCs with two or more
Ethernet devices, for these we need to pass IRQF_SHARED to request_irq().  Add
the 'irq_flags' field to the 'struct sh_eth_cpu_data' instead of #ifdef'fery.

Subject: sh_eth: consolidate sh_eth_reset()

This driver has sh_eth_reset() function for each SoC and this function is almost
always the same, except for the several a bit different variations for Gigabit
Ethernet.  Consolidate every variation into a single function -- which allows
us to get  rid of some more #ifdef'fery.

Subject: sh_eth: enclose PM code into #ifdef CONFIG_PM

Put '#ifdef CONFIG_PM' around sh_eth_runtime_nop() and 'sh_eth_dev_pm_ops'.
Add '#define SH_ETH_PM_OPS' to facilitate initialization of driver's 'pm' field
depending on whether CONFIG_PM is enabled.

Subject: net/macb: increase RX buffer size for GEM

Macb Ethernet controller requires a RX buffer of 128 bytes. It is
highly sub-optimal for Gigabit-capable GEM that is able to use
a bigger DMA buffer. Change this constant and associated macros
with data stored in the private structure.
RX DMA buffer size has to be multiple of 64 bytes as indicated in
DMA Configuration Register specification.

Subject: net/macb: change RX path for GEM

GEM is able to adapt its DMA buffer size, so change
the RX path to take advantage of this possibility and
remove all kind of memcpy in this path.
This modification introduces function pointers for managing
differences between MACB and GEM adapter type.

Subject: fec: Only pass pdev in fec_ptp_init()

Passing pdev in fec_ptp_init() is enough, since we can get ndev locally.

From 303d1cbf610eef31e039efc2e8da30cf94cf5ebc Mon Sep 17 00:00:00 2001
From: Jay Vosburgh <fubar@us.ibm.com>

Subject: bonding: Convert hw addr handling to sync/unsync, support ucast
 addresses

This patch converts bonding to use the dev_uc/mc_sync and
dev_uc/mc_sync_multiple functions for updating the hardware addresses
of bonding slaves.

	The existing functions to add or remove addresses are removed,
and their functionality is replaced with calls to dev_mc_sync or
dev_mc_sync_multiple, depending upon the bonding mode.

	Calls to dev_uc_sync and dev_uc_sync_multiple are also added,
so that unicast addresses added to a bond will be properly synced with
its slaves.

	Various functions are renamed to better reflect the new
situation, and relevant comments are updated.

Subject: bonding: disallow change of MAC if fail_over_mac enabled

Currently, if fail_over_mac is set to active, then attempts to
change the MAC of the bond itself silently fail.  However, if fail_over_mac
is set to follow, changes are permitted.

	Permitting the bond's MAC to change with fail_over_mac=follow
will disrupt the follow functionality, which normally controls the
assignment of MAC address to the bond and its slaves, and can cause
multiple ports to be assigned the same MAC address. which will interfere
with the functioning of the device (where the device here is a
virtualization-aware card for s390, qeth).

Subject: sh_eth: create initial ID table

We are trying to get away from the current driver's scheme of identifying a SoC
based on #ifdef's and the platform device ID table matching seems to be a good
replacement -- we can use the 'driver_data' field of 'struct platform_device_id'
as a pointer to a 'struct sh_eth_cpu_data'. Start by creating the initial table
with driver's name as the only entry without the driver data. Check  the driver
data in the probe() method and if it's not NULL override 'mdp->cd' from it.

Subject: sh_eth: get SH7757 support out of #ifdef

Get the SH7757 code/data in the driver out of #ifdef by adding "sh7757-ether"
and "sh7757-gether" to the platform driver's ID table.  Note that we can remove
SH_ETH_HAS_BOTH_MODULES and sh_eth_get_cpu_data().
Change the Ether/GEther platform devices' names in the SH platform code
accordingly.

Subject: sh_eth: get R8A777x support out of #ifdef

Get the R-Car code/data in the driver out of #ifdef by adding "r8a777x-ether" to
the platfrom driver's  ID table; since it's the last #ifdef, we remove CARDNAME
from the  ID table and no longer check  the driver data before  assigning it to
'mdp->cd'...
Change the Ether platform device's name in the ARM platform code accordingly.

Subject: sh_eth: remove dependencies from Kconfig

Since dependence on the certain SoCs is no  longer  necessary to compile the
driver, remove the dependency list from its Kconfig entry which is a popular
demand anyway...

Subject: macvtap: fix a possible race between queue selection and changing
 queues

Complier may generate codes that re-read the vlan->numvtaps during
macvtap_get_queue(). This may lead a race if vlan->numvtaps were changed in the
same time and which can lead unexpected result (e.g. very huge value).

We need prevent the compiler from generating such codes by adding an
ACCESS_ONCE() to make sure vlan->numvtaps were only read once.

Subject: macvtap: eliminate linear search

Linear search were used in both get_slot() and macvtap_get_queue(), this is
because:

- macvtap didn't reshuffle the array of taps when create or destroy a queue, so
  when adding a new queue, macvtap must do linear search to find a location for
  the new queue. This will also complicate the TUNSETQUEUE implementation for
  multiqueue API.
- the queue itself didn't track the queue index, so the we must do a linear
  search in the array to find the location of a existed queue.

The solution is straightforward: reshuffle the array and introduce a queue_index
to macvtap_queue.

Subject: macvtap: add TUNSETQUEUE ioctl

This patch adds TUNSETQUEUE ioctl to let userspace can temporarily disable or
enable a queue of macvtap. This is used to be compatible at API layer of tuntap
to simplify the userspace to manage the queues. This is done through introducing
a linked list to track all taps while using vlan->taps array to only track
active taps.

Subject: cw1200: Sanity-check arguments in copy_from_user()

The optional debugfs interface to the vendor's engineering tools wasn't
bounds checking at all, which made it trivial to perform a buffer
overflow if this interface was compiled in and then explicitly enabled
at runtime.

This patch checks both the length supplied as part of the data to ensure
it is sane, and also the amount of data compared to the remaining buffer
space.  If either is too large, fail immediately.

Date: Mon, 3 Jun 2013 23:39:53 +0200
Subject: rt2x00: rt2x00queue: initialize data_queue fields earlier

Support for rt2800 device is broken since my
'rt2x00: rt2x00dev: use rt2x00dev->tx->limit'
patch. The changelog of that commit says that the
TX data queue is initialized already when the
rt2x00lib_probe_hw() function is called.

However as Jakub noticed it, this statement is not
correct. The queue->limit field is initialized in
the rt2x00queue_alloc_entries routine and that is
not yet called when rt2x00lib_probe_hw() runs.
Because the value of tx->limit contains zero, the
driver tries to allocate a kernel fifo with zero
size and kfifo_alloc rejects that with -EINVAL.

  PCI: Enabling device 0000:01:00.0 (0000 -> 0002)
  ieee80211 phy1: rt2x00_set_rt: Info - RT chipset 3071, rev 021c detected
  ieee80211 phy1: rt2x00_set_rf: Info - RF chipset 0008 detected
  ieee80211 phy1: rt2x00lib_probe_dev: Error - Failed to initialize hw
  rt2800pci: probe of 0000:01:00.0 failed with error -22

Move the data_queue field initialization from
the rt2x00queue_alloc_entries routine into the
rt2x00queue_init function. The initialization
code is not strictly related to the allocation,
and the change ensures that the queue_data fields
can be used in the probe routines.

The patch also introduces a helper function in
order to be able to get the correct data_queue_desc
structure for a given queue. This helper is only
needed temporarily and it will be removed later.

Subject: bcm63xx_enet: split DMA channel register accesses

The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:

- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space

This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

Subject: bcm63xx_enet: add support for Broadcom BCM63xx integrated gigabit
 switch

Newer Broadcom BCM63xx SoCs: 6328, 6362 and 6368 have an integrated switch
which needs to be driven slightly differently from the traditional
external switches. This patch introduces changes in arch/mips/bcm63xx in order
to:

- register a bcm63xx_enetsw driver instead of bcm63xx_enet driver
- update DMA channels configuration & state RAM base addresses
- add a new platform data configuration knob to define the number of
  ports per switch/device and force link on some ports
- define the required switch registers

On the driver side, the following changes are required:

- the switch ports need to be polled to ensure the link is up and
  running and RX/TX can properly work
- basic switch configuration needs to be performed for the switch to
  forward packets to the CPU
- update the MIB counters since the integrated

Subject: ixgbe: add support for ndo_ll_poll

Add the ixgbe driver code implementing ndo_ll_poll.
Adds ndo_ll_poll method and locking between it and the napi poll.
When receiving a packet we use skb_mark_ll to record the napi it came from.
Add each napi to the napi_hash right after netif_napi_add().

From 19db577868e94c80dc9a569d937109f95c34d0f4 Mon Sep 17 00:00:00 2001
From: Solomon Peachy <pizza@shaftnet.org>
Date: Tue, 11 Jun 2013 09:49:39 -0400
Subject: cw1200: Eliminate the ETF debug/engineering code.

This is only really useful for people who are bringing up new hardware
designs and have access to the proprietary vendor tools that interface
with this mode.

It'll live out of tree until it's rewritten to use a less kludgy interface.

Subject: 3c59x: consolidate error cleanup in vortex_init_one()

The PCI driver's probe() method  duplicates the error cleanup code each time it
has to do error exit. Consolidate the error cleanup code  in  one place and use
*goto* to jump to the right places.

Subject: team: remove synchronize_rcu() called during queue override change

This patch removes synchronize_rcu() from function
__team_queue_override_port_del(). That can be done because it is ok to
do list_del_rcu() and list_add_tail_rcu() on the same list_head member
without calling synchronize_rcu() in between. A bit of refactoring
needed to be done because INIT_LIST_HEAD needed to be removed (to not
kill the forward pointer) as well.

Subject: sfc: Store port number in private data, not net_device::dev_id

We should not use net_device::dev_id to indicate the port number, as
this affects the way the local part of IPv6 addresses is normally
generated.

This field was intended for use where multiple devices may share a
single assigned MAC address and need to have different IPv6 addresses.
Siena's two ports each have their own MAC addresses.

Subject: gianfar: Add backwards compatible Single Queue mode polling

Older Single Queue (SQ_SG_MODE) devices like TSEC (i.e. mpc83xx)
don't feature the frame receive indication bits (RXF) in RSTAT.
For these and for the rest of the SQ_SG_MODE devices, provide the
appropiate polling routine that handles a single pair of Rx/Tx
BD rings, removing the overhead incurred by the multiple queues/
multiple interrupt group devices (veTSEC/ eTSEC2.0 devices).
So this is primarily a fix for the TSEC devices.

Subject: ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices

Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.

The wiki page for the driver is:

http://wireless.kernel.org/en/users/Drivers/ath10k

The driver has had many authors, they are listed here alphabetically:

Bartosz Markowski <bartosz.markowski@tieto.com>
Janusz Dziedzic <janusz.dziedzic@tieto.com>
Kalle Valo <kvalo@qca.qualcomm.com>
Marek Kwaczynski <marek.kwaczynski@tieto.com>

+ * Bootloader Messaging Interface (BMI)
+ *
+ * BMI is a very simple messaging interface used during initialization
+ * to read memory, write memory, execute code, and to define an
+ * application entry PC.
+ *
+ * It is used to download an application to QCA988x, to provide
+ * patches to code that is already resident on QCA988x, and generally
+ * to examine and modify state.  The Host has an opportunity to use
+ * BMI only once during bootup.  Once the Host issues a BMI_DONE
+ * command, this opportunity ends.
+ *
+ * The Host writes BMI requests to mailbox0, and reads BMI responses
+ * from mailbox0.   BMI requests all begin with a command
+ * (see below for specific commands), and are followed by
+ * command-specific data.
+ *
+ * Flow control:
+ * The Host can only issue a command once the Target gives it a
+ * "BMI Command Credit", using AR8K Counter #4.  As soon as the
+ * Target has completed a command, it issues another BMI Command
+ * Credit (so the Host can issue the next command).
+ *
+ * BMI handles all required Target-side cache flushing.

+ * A single CopyEngine (CE) comprises two "rings":
+ *   a source ring
+ *   a destination ring
+ *
+ * Each ring consists of a number of descriptors which specify
+ * an address, length, and meta-data.
+ *
+ * Typically, one side of the PCIe interconnect (Host or Target)
+ * controls one ring and the other side controls the other ring.
+ * The source side chooses when to initiate a transfer and it
+ * chooses what to send (buffer address, length). The destination
+ * side keeps a supply of "anonymous receive buffers" available and
+ * it handles incoming data as it arrives (when the destination
+ * recieves an interrupt).
+ *
+ * The sender may send a simple buffer (address/length) or it may
+ * send a small list of buffers.  When a small list is sent, hardware
+ * "gathers" these and they end up in a single destination buffer
+ * with a single interrupt.
+ *
+ * There are several "contexts" managed by this layer -- more, it
+ * may seem -- than should be needed. These are provided mainly for
+ * maximum flexibility and especially to facilitate a simpler HIF
+ * implementation. There are per-CopyEngine recv, send, and watermark
+ * contexts. These are supplied by the caller when a recv, send,
+ * or watermark handler is established and they are echoed back to
+ * the caller when the respective callbacks are invoked. There is
+ * also a per-transfer context supplied by the caller when a buffer
+ * (or sendlist) is sent and when a buffer is enqueued for recv.
+ * These per-transfer contexts are echoed back to the caller when
+ * the buffer is sent/received.

+ *   may involve waking the Target from a low power state, which

+ *
+ *   Use ath10k_pci_sleep to tell the Target that as far as

+ *		phy_error is asserted if the rx_clear does not assert before
+ *		the end of the PHY error.
+ *
+ * wb_timestamp
+ *		WLAN/BT timestamp is a 1 usec resolution timestamp which
+ *		does not get updated based on receive beacon like TSF.  The
+ *		same rules for capturing tsf_timestamp are used to capture
+ *		the wb_timestamp.
+ *
+ * locationing_timestamp
+ *		Timestamp used for locationing.  This timestamp is used to
+ *		indicate fractions of usec.  For example if the MAC clock is
+ *		running at 80 MHz, the timestamp will increment every 12.5
+ *		nsec.  The value starts at 0 and increments to 79 and
+ *		returns to 0 and repeats.  This information is valid for
+ *		every PPDU.  This information can be used in conjunction
+ *		with wb_timestamp to capture large delta times.
+ *
+ * phy_err_code
+ *		See the 1.10.8.1.2 for the list of the PHY error codes.
+ *
+ * phy_err
+ *		Indicates a PHY error was detected for this PPDU.
+ *
+ * rx_location
+ *		Indicates that location information was requested.
+ *
+ * txbf_h_info
+ *		Indicates that the packet data carries H information which
+ *		is used for TxBF debug.

+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * rx_antenna
+ *		Receive antenna value
+ *
+ * tx_ht_vht_ack
+ *		Indicates that a HT or VHT Ack/BA frame was transmitted in
+ *		response to this receive packet.
+ *
+ * bb_captured_channel
+ *		Indicates that the BB has captured a channel dump.  FW can
+ *		then read the channel dump memory.  This may indicate that
+ *		the channel was captured either based on PCU setting the
+ *		capture_channel bit  BB descriptor or FW setting the
+ *		capture_channel mode bit.
+ *
+ * reserved_19
+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * bb_length
+ *		Indicates the number of bytes of baseband information for
+ *		PPDUs where the BB descriptor preamble type is 0x80 to 0xFF
+ *		which indicates that this is not a normal PPDU but rather
+ *		contains baseband debug information.
+ *
+ * reserved_20
+ *		Reserved: HW should fill with 0, FW should ignore.
+ *
+ * ppdu_done
+ *		PPDU end status is only valid when ppdu_done bit is set.
+ *		Every time HW sets this bit in memory FW/SW must clear this

+/*
+ * This file specifies the WMI interface for the Unified Software
+ * Architecture.
+ *
+ * It includes definitions of all the commands and events. Commands are
+ * messages from the host to the target. Events and Replies are messages
+ * from the target to the host.
+ *
+ * Ownership of correctness in regards to WMI commands belongs to the host
+ * driver and the target is not required to validate parameters for value,
+ * proper range, or any other checking.
+ *
+ * Guidelines for extending this interface are below.
+ *
+ * 1. Add new WMI commands ONLY within the specified range - 0x9000 - 0x9fff
+ *
+ * 2. Use ONLY u32 type for defining member variables within WMI
+ *    command/event structures. Do not use u8, u16, bool or
+ *    enum types within these structures.
+ *
+ * 3. DO NOT define bit fields within structures. Implement bit fields
+ *    using masks if necessary. Do not use the programming language's bit
+ *    field definition.
+ *
+ * 4. Define macros for encode/decode of u8, u16 fields within
+ *    the u32 variables. Use these macros for set/get of these fields.
+ *    Try to use this to optimize the structure without bloating it with
+ *    u32 variables for every lower sized field.
+ *
+ * 5. Do not use PACK/UNPACK attributes for the structures as each member
+ *    variable is already 4-byte aligned by virtue of being a u32
+ *    type.
+ *
+ * 6. Comment each parameter part of the WMI command/event structure by
+ *    using the 2 stars at the begining of C comment instead of one star to
+ *    enable HTML document generation using Doxygen.

Subject: ath9k: Fix OFDM weak signal detection for AP mode

The commit "ath9k_hw: improve ANI processing and rx desensitizing parameters"
changed the OFDM weak signal detection logic to disable it
for AP mode, which is not allowed. Fix this and enable it always
for AP mode.

Subject: ath9k: Fix ANI monitoring

The commit "ath9k_hw: improve ANI processing and rx desensitizing parameters"
changed various ANI operational parameters to address a specific
card/environment. This is not really applicable for other cards
in general usage.

As per internal documentation, lowering the immunity level can be
done only after 5 periods have passed and the CCK/OFDM errors are
below the low watermak threshold - which have been fixed at 300 and
400 respectively by the sytems team.

Raising the immunity level can be done when CCK/OFDM errors exceed
600 and 1000 (per second).

Set these values once during attach.

Subject: ath9k: Fix ofdm weak signal configuration

The commit, "ath9k_hw: improve ANI processing and rx desensitizing parameters"
removed code setting various phy registers holding threshold values.

This is likely required for OFDM weak signal detection to function
correctly, so add them, but skip AR9462 and AR9565.

Subject: rt2x00: rt2x00queue: add priv_size field to struct data_queue

Add a new field into struct data_queue and store
the size of the per-queue_entry private data in
that. Additionally, use the new field in the
rt2x00queue_alloc_entries function to compute
the size of the queue entries for a given queue.

The patch does not change the current behaviour
but makes it possible to remove the queue_desc
parameter of the rt2x00queue_alloc_entries function.
That will be done by a subsequent patch.

Subject: rt2x00: rt2x00dev: use rt2x00dev->bcn->limit

The beacon data queue is initialized already,
so fetch the number of the queue entries from
that instead of using the entry_num field of
the data queue descriptor.

The two values are the same, and the use of the
rt2x00dev->bcn->limit value allows us to get rid
of a superfluous pointer dereference.

Use the queue->limit value instead of the

The two source values are the same and the

removed by a later patch.

Also separate the computation from the rest

Subject: rt2x00: add queue_init callback to rt2x00_ops

The driver uses static data structures for initializing
specific fields of a given data queue. These static
queue data descriptor structures are containing values
which related to a given chipset.

Even though the values are chip specific, the actual
selection of the used structure is based on device
specific vendor/product identifiers. This approach works,
but it is not always reliable. Sometimes the vendor and/or
device IDs of the PCI and USB devices contains improper
values which makes it impossible to select the correct
structure for such devices.

The patch adds a new callback to tr2x00_ops which
is called after the chipset detection is finished.
This allows the drivers to do dynamic initialization
of the data_queue structure for a given queue based
on the actual chipset.

After each driver implements the queue_init callback,
the data_queue_desc structure will be removed.

Subject: rt2x00: rt2800usb: implement queue_init callback

The generic rt2x00 code has been changed to allow the
drivers toimplement dynamic data_queue initialization.

Remove the static data queue descriptor structures
and implement the queue_init callback instead.

The actual chipset is already known when the callback
is used. This allows us to use a single callback for
all supported devices.

Subject: rt2x00: rt2500usb: implement queue_init callback

The generic rt2x00 code has been changed to allow the
drivers toimplement dynamic data_queue initialization.

Remove the static data queue descriptor structures
and implement the queue_init callback instead.

Compile tested only.

Subject: rt2x00: remove data_queue_desc struct

If the queue_init callback is implemented
by a driver it gets used instead of the
data_queue_desc based initialization.

The queue_init callback is implemented for
each drivers now, so the old initialization
method is not used anymore. Remove the unused
data_queue_desc structure and all of the
related code.

Subject: mwifiex: fix regression issue for usb interface

PATCH "mwifiex: scan delay timer cleanup in unload path" adds code
to cancel scan delay timer in unload path. It causes a regression
for USB interface.

USB8797 card gets enumerated twice. First enumeration is for
firmware download and second enumeration expects firmware
initialization.

It was observed that we are trying del_timer_sync() without setting
up the timer when remove handler is called after first enumeration.

This patch moves setup_timer() call to appropriate place so that
timer is setup for both the enumerations.

Subject: rt2x00: move extra_tx_headroom field from rt2x00_ops to rt2x00_dev

The extra_tx_headroom field of struct rt2x00_ops
indicates the extra TX headroom size required for
a given device. This data is redundant, the value
can be computed from the desc_size and winfo_size
fields of the TX queues.

Move the extra_tx_headroom field to struct rt2x00_dev,
compute its value in the probe routine and use the
cached value in the rest of the code.

Subject: brcmfmac: allow firmware-signal tlv to be longer than specified

The firmware-signal API specification defines length for the different
tlv. During testing on different devices it turned out not all firmware
used the tlv length according specification. Therefore the length check
is made less strict with this patch.

The brcmf_skbuff_cb structure contain if_flags and htod fields. Both
have a bitfield defined to hold the fifo number. With a small code
change we get rid of the fifo bitfield in if_flags.

Subject: brcmfmac: Take bus flowcontrol at credit mgmt into account.

On bus flow control (no more host bus resources to send packets
to device) the netif flow control was toggled, however credit
management should also take this status into account. Since there
are multiple sources handling this flow control necessary spinlocks
were added to protect flow control related data/states.

Subject: brcmfmac: explicitly indicate sk_buff is sent upon request credit

Firmware can request the driver for transmit packets using two different
signals. Only for one signal a flag was set in the sk_buff control
buffer. This patch adds explicit flag for the other signal as well.

Subject: brcmfmac: reducing debug logging in firmware-signalling code

The debug logging in firmware-signalling code was rather extensive and
for a large part in the data path. This patch removes large part or the
level is changed to DATA level.

Subject: brcmfmac: On bus flow control use fw signalling or netif.

Currently on a bus flow control both fws is informed and netif queue
gets closed. In case of fw signalling enabled, let the flow control
be handled by fw signalling only.

When credit borrowing is active the BE credits have been depleted,
however the worker should still be scheduled. In case of credit
borrowing correct credit map to make sure worker remains active.

The BDC header contains PropTx TLV signals that are useful to capture
for debugging. This event captures the header and tlv's in binary
form. This can be post-processed using trace-cmd plugin.

Subject: brcmfmac: increment hard_header_len instead of overriding

In brcmf_net_attach() the hard_header_len is set to sum of ETH_HLEN
and the headroom needed by the bus interface. Better use increment
instead as hard_header_len is already initialized upon alloc_netdev().

Subject: brcmfmac: Sent TIM information in case of data available.

When data is available and fw signalling is enabled then TIM
information should be sent to firmware. If it can piggy back
on existing packet then do that otherwise create dummy packet
to get information out.

Subject: brcmfmac: free primary net_device when brcmf_bus_start() fails

When initialization within brcmf_bus_start() fails on steps
before the brcmf_net_attach() the net_device for the primary
interface needs to be freed.

This patch resolves a panic during kernel boot as reported
by Stephen Warren.

Subject: ath9k: limit multicast buffer hardware queue depth

The CAB (Content after Beacon) queue is used for beacon-triggered
transmission of buffered multicast frames. If lots of multicast frames
were buffered and this queue fills up, it drowns out all regular
traffic. To limit the damage that buffered traffic can do, try to limit
the queued data to becaon_interval / 8.

WMI PCP Start flow should not be handled through:
net_device_ops->ndo_open()->wil_up()->__wil_up()
because it missing mandatory FW parameters (SSID,Channel,IEs, Security...).

Prior to AP starting __wil_up() may be called with iftype set
cfg80211_ops->change_virtual_intf(NL80211_IFTYPE_AP or STATION)
depend on the application hostapd/wpa_supplicant/iw.
there should not be an attempt to start an AP flow,
AP/PCP start flow will be started latter by cfg80211_ops->start_ap().

All known ar7010+ar* device and current FW support STBC TX. This patch
make use of it and suggest to send STBC if peer support it.
I use wort "suggest" since currenly we have separate rate controller
in FW which will make decision based on rate and hardware.

Subject: b43: ensue that BCMA is "y" when B43 is "y"

When b43 gets build into the kernel and it should use bcma we have to
ensure that bcma was also build into the kernel and not as a module.
In this patch this is also done for SSB, although you can not
build b43 without ssb support for now.

This fixes a build problem reported by Randy Dunlap in
5187EB95.2060605@infradead.org

Subject: ath9k: Fix noisefloor calibration

The commits,

"ath9k: Fix regression in channelwidth switch at the same channel"
"ath9k: Fix invalid noisefloor reading due to channel update"

attempted to fix noisefloor calibration when a channel switch
happens due to HT20/HT40 bandwidth change. This is causing invalid
readings resulting in messages like:

"ath: phy16: NF[0] (-45) > MAX (-95), correcting to MAX".

This results in an incorrect noise being used initially for reporting
the signal level of received packets, until NF calibration is done
and the history buffer is updated via the ANI timer, which happens
much later.

When a bandwidth change happens, it is appropriate to reset
the internal history data for the channel. Do this correctly in the
reset() routine by checking the "chanmode" variable.

Subject: ath9k: Do not assign noise for NULL caldata

ah->noise is maintained globally and not per-channel. This
is updated in the reset() routine after the NF history has been
filled for the *current channel*, just before switching to
the new channel. There is no need to do it inside getnf(), since
ah->noise must contain a value for the new channel.

Subject: iwl4965: workaround for firmware frame tx rejection

Firmware can reject to transmit frame on passive channel, when it
did not yet received any frame with valid CRC on that channel.
Workaround this problem in the driver.

Subject: brcmfmac: Always use fifo_credits, also for requested credits.

Currently firmware requested credits do not require fifo credits.
From a buffer management point of view this is incorrect. So
firwmware requested credits require also fifo credits before the
packet can be transferred to the host.

Subject: sh_eth: split 'sh_eth_netdev_ops'

Commit 9f86134155047720a3685cda21467f68695152d2 (sh_eth: remove SH_ETH_HAS_TSU)
removes 'const' from 'sh_eth_netdev_ops'  and modifies it in case TSU registers
are present. I've originally suggested to Iwamatsu-san to split  this structure
in two instead and afterwards Dave M. suggested doing the same.
Split 'sh_eth_netdev_ops_tsu' from 'sh_eth_netdev_ops', making both 'const', and
assigning 'ndev->detdev_ops'  depending on the presence of TSU registers.

Subject: tun: Report "persist" flag to userspace

The TUN_PERSIST flag is not reported at all -- both TUNGETIFF, and sysfs
"flags" attribute skip one. Knowing whether a device is persistent or not
is critical for checkpoint-restore, thus I propose to add the read-only
IFF_PERSIST one for this.

Setting this new IFF_PERSIST is hardly possible, as TUNSETIFF doesn't check
for unknown flags being zero and thus there can be trash.

Subject: cxgb4: Do not set net_device::dev_id to VI index

net_device::dev_id should not be used merely to indicate a VI index,
as it affects the way the local part of IPv6 addresses is normally
generated.

This field was intended for use where multiple devices may share a
single assigned MAC address and need to have different IPv6 addresses.
T4 VIs each have their own MAC address.

Subject: iwlwifi: pcie: don't read INTA register in ICT IRQ handler

There's no reason to read the INTA register in the ICT IRQ
handler, this interrupt mechanism is designed to not have
to read as many registers as the regular one. Not reading
the INTA register gives a significant performance/CPU use
improvement.

Since we still want to get this info, fetch it only if
the ISR debug level is enabled.

Subject: iwlwifi: reduce debug ifdefs using the optimiser

Instead of using #ifdef CONFIG_IWLWIFI_DEBUG, remove the
iwlwifi_mod_params.debug_level variable completely and
make iwl_have_debug_level() always return false in the
non-debug case. This way, the optimiser will elide all
code for it automatically without having to add #ifdefs.

Subject: iwlwifi: create opmode/device dependencies

The older devices (pre-7000/3000 series) all only work with the
DVM opmode due to firmware availability, while newer ones will
only work with the MVM opmode for the same reason.

When building a driver that only has one of MVM or DVM, there's
no reason to build the device support and have the PCIe IDs for
all devices since they can't be used anyway, so avoid that.

Subject: iwlwifi: pcie: fix race in queue unmapping

When a queue is disabled, it frees all its entries. Later,
the op_mode might still get notifications from the firmware
that triggers to free entries in the tx queue. The transport
should be prepared for these races and know to ignore
reclaim calls on queues that have been disabled and whose
entries have been freed.

Subject: iwlwifi: pcie: wake the queue if stopped when being unmapped

When the queue is unmapped while it was so loaded that
mac80211's was stopped, we need to wake the queue after
having freed all the packets in the queue.
Not doing so can result in weird stuff like:

* run lots of traffic (mac80211's queue gets stopped)
* RFKILL
* de-assert RFKILL
* no traffic

Subject: carl9170: add support for the new rate control API

With the new rate control API, the driver can now apply the
tx rate to outgoing frames just before they are uploaded to
the device. This is important because the rate control can
now react to fading or improving links a bit sooner.

Also, the driver no longer needs to sort the outgoing frames
for sample attempts (which affected the size of A-MPDUs and
the throughput of the link). For aggregated data frames, the
driver (and rate control) needs only to calculate and apply
a single set of tx rates to every subframe of the whole
aggregate.

0x01fe according to the NFC Digital Specification.
By checking those first 2 bytes we send the right command either to the
reader gate when NFCID2 != 0x1fe (The NFC tag case) or to the NFCIP1 gate
when seeing an NFC DEP device (The NFC peer to peer case).

Without this fix, Felica (Type F) tags are not properly detected with this
driver.

Subject: NFC: pn544: Remove Felica and Jewel device presence check

There is no builtin command for driver to check the presence of
Felica and Jewel device, it is more reasonable for the userspace
daemon neard to build seperate commands to check the presence of
the card.

Subject: NFC: NCI: Fix skb->dev usage

skb->dev is used for carrying a net_device pointer and not
an nci_dev pointer.

Remove usage of skb-dev to carry nci_dev and replace it by parameter
in nci_recv_frame(), nci_send_frame() and driver send() functions.

NfcWilink driver is also updated to use those functions.

Subject: bcm63xx_enet: add support Broadcom BCM6345 Ethernet

This patch adds support for the Broadcom BCM6345 SoC Ethernet. BCM6345
has a slightly different and older DMA engine which requires the
following modifications:

- the width of the DMA channels on BCM6345 is 64 bytes vs 16 bytes,
  which means that the helpers enet_dma{c,s} need to account for this
  channel width and we can no longer use macros

- BCM6345 DMA engine does not have any internal SRAM for transfering
  buffers

- BCM6345 buffer allocation and flow control is not per-channel but
  global (done in RSET_ENETDMA)

- the DMA engine bits are right-shifted by 3 compared to other DMA
  generations

- the DMA enable/interrupt masks are a little different (we need to
  enabled more bits for 6345)

- some register have the same meaning but are offsetted in the ENET_DMAC
  space so a lookup table is required to return the proper offset

The MAC itself is identical and requires no modifications to work.

Subject: NFC: pn533: Copy NFCID2 through ATR_REQ

When using NFC-F we should copy the NFCID2 buffer that we got from

Subject: NFC: Remove the static supported_se field

Supported secure elements are typically found during a discovery process
initiated when the NFC controller is up and running. For a given NFC
chipset there can be many configurations (embedded SE or not, with or
without a SIM card wired to the NFC controller SWP interface, etc...) and
thus driver code will never know before hand which SEs are available.
So we remove this field, it will be replaced by a real SE discovery
mechanism.

Subject: NFC: pn533: Fix ACR122 related debug output

Instead of dumping ACR122 frames as errors, we use the print_hex_dump()
dynamic debug APIs.
We also print an accurate IC version, as the ACR122 is pn532 based.

Subject: NFC: Add a nfc hardware simulation driver

This driver declares two virtual NFC devices supporting NFC-DEP protocol.
An LLCP connection can be established between them and all packets sent
from one device is sent back to the other, acting as loopback devices.

Once established, the LLCP link can be disconnected by disabling the target
device (with rfkill, nfctool, or neard disable-adapter test script).

Subject: ath9k: Add custom parameters for CUS198

CUS198 is a card based on AR9485. There are differences
between the base reference design HB125 and CUS198.
Identify such cards based on the PCI subsystem IDs and
set HW parameters appropriately.

Addresses this bug - https://bugzilla.kernel.org/show_bug.cgi?id=49201

Subject: orinoco_usb: fix memory leak in ezusb_access_ltv() when device
 disconnected

If "device is disconnected" check occurs to be true in ezusb_access_ltv(),
it just return -ENODEV. But that means request_context is leaked since
there are no any references to it anymore.
The patch adds a call to ezusb_request_context_put() before return.

Found by Linux Driver Verification project (linuxtesting.org).

Subject: wl18xx: FDSP Code RAM Corruption fix

In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

Subject: wlcore: configure rates in multiple cases

The current code configures the peer caps only on BSS_CHANGED_HT
notification. However, we have to configure the peer caps
(and rates) even when HT is not enabled. Otherwise, the fw
continues working with low rates.

Configure the peer caps when sta_exists is true (i.e. when
we extracted the sta rates, e.g. on association).

Subject: wl18xx: use locally administered MAC address if not available from
 fuse

In some R&D chips, the device may be left untrimmed and with the MAC
address missing from fuse ROM.  In order to support those devices,
apply a random locally administered MAC address instead.

Subject: wlcore: fix occasional AP TX stop after recovery

The fw_status wasn't zeroed during allocation, resulting
in uninitialized var usage, and finally causing AP
traffic stop after recovery.

The wrong value in fw_status_2->counters.tx_lnk_free_pkts
led to a bad lnk->allocated_pkts calculation in
wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return
FALSE (lnk->allocated_pkts > thold).
This eventually blocked the link in wlcore_tx_work_locked(),
as wl1271_skb_dequeue() continuously returned NULL.

Fix it by zeroing wl->fw_status_1/2 during allocation.

Subject: iwlwifi: bump required firmware API version for 3160/7260

As the firmware API has changed significantly and we don't
have support code for the old APIs, bump the version to be
able to release the version 7 API firmware. Unfortunately
this means that the driver in 3.9 and 3.10 can't work, but
that's still better than crashing the device/driver there.

Subject: mwifiex: fix memory corruption when unsetting multicast list

When trying to unset a previously-set multicast list (i.e. the new list
has 0 entries), mwifiex_set_multicast_list() was calling down to
mwifiex_request_set_multicast_list() while leaving
mcast_list.num_multicast_addr as an uninitialized value.

We were arriving at mwifiex_cmd_mac_multicast_adr() which would then
proceed to do an often huge memcpy of
mcast_list.num_multicast_addr*ETH_ALEN bytes, causing memory corruption
and hard to debug crashes.

Fix this by setting mcast_list.num_multicast_addr to 0 when no multicast
list is provided. Similarly, fix up the logic in
mwifiex_request_set_multicast_list() to unset the multicast list that
was previously sent to the hardware in such cases.

The commit "ath9k: Fix ANI monitoring" reverted an earlier
commit that adjusted ANI to improve performance. But, this causes
adverse effects in AP mode (as reported by Felix based on an OpenWrt
report). Use the older INI/period configuration for now until more
testing is done.

Subject: tg3: Prevent system hang during repeated EEH errors.

The current tg3 code assumes the pci_error_handlers to be always called
in sequence.  In particular, during ->error_detected(), NAPI is disabled
and the device is shutdown.  The device is later reset and NAPI
re-enabled in ->slot_reset() and ->resume().

In EEH, if more than 6 errors are detected in a hour, only
->error_detected() will be called.  This will leave the driver in an
inconsistent state as NAPI is disabled but netif_running state is still
true.  When the device is later closed, we'll try to disable NAPI again
and it will loop forever.

We fix this by closing the device if we encounter any error conditions
during the normal sequence of the pci_error_handlers.

v2: Remove the changes in tg3_io_resume() based on Benjamin Poirier's
    feedback.

Subject: bonding: don't call alb_set_slave_mac_addr() while atomic

alb_set_slave_mac_addr() sets the mac address in alb mode via
dev_set_mac_address(), which might sleep. It's called from
alb_handle_addr_collision_on_attach() in atomic context (under
read_lock(bond->lock)), thus triggering a bug.

Fix this by moving the lock inside alb_handle_addr_collision_on_attach().

v1->v2:
As Nikolay Aleksandrov noticed, we can drop the bond->lock completely.
Also, use bond_slave_has_mac(), when possible.

Subject: mv643xx_eth.c: convert skb->end into skb_end_poitner(skb)

The change set of 4305b541 "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().

Since arm or ppc arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.
But this patch is good for consistency.

Found by inspection. Compile test only.

The change set of 7a884dc "[SK_BUFF]: Convert skb->tail to sk_buff_data_t"

Subject: iwlwifi: mvm: allow firmware crashes to wake system for debug

When the D3 firmware crashes, it can be helpful for debugging to
resume the system to get the SRAM snapshot to see why it crashed.
Allow enabling this with a debugfs option.

From 49464ae502680e362be519ac024a0f5998faaa7e Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 17 Jun 2013 23:13:31 +0200
Subject: iwlwifi: remove testmode

The old nl80211 testmode is no longer useful in iwlwifi,
we're moving towards a new model internally and there's
no open tool to use it, so remove it.

Subject: ath9k: Modify IDs to identify CUS230

CUS198 and CUS230 are similar cards, both
are AR9485 + xLNA solutions. But, the subsystem IDs
differ - identify CUS230 explicitly to make things
clearer.

Subject: ssb: register serial flash as platform device
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This allows writing MTD driver working as a platform driver. In
platform_data it will receive struct ssb_sflash, which contains all
important data about flash (window, size).

Subject: brcmfmac: remove dependency with nl80211.h

The firmware-signalling code used NL80211_NUM_ACS, but it has
its own definition enum brcmf_fws_fifo, which is more appropriate
to use. This effectively removes the need to include nl80211.h.

Subject: brcmfmac: replace brcmf_sdioh_request_buffer with brcmf_sdio_buffrw

Introducing a new SDIO block data access interface function
brcmf_sdio_buffrw. It will act as a unified interface function for any block
data access to WiFi dongle through SDIO interface. This patch enables
the support for single skb transmission.

Subject: bcm63xx_enet: fix return value check in bcm_enet_shared_probe()

In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

Subject: rtlwifi: rtl8192cu: Fix duplicate if test

A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the
same condition twice. The problem was found using cppcheck-1.49, and the
proper fix was verified against the pre-mac80211 version of the code.

This patch was originally included as commit 1288aa4, but was accidentally
reverted in a later patch.

This patch adds code to parse requested AP's 11h capabilities
and add 11h information in association request.

Also, deauth is sent to the AP after receiving channel switch
announcement event from firmware. This happens when AP advertises
WLAN_EID_CHANNEL_SWITCH IE in it's beacon.

Subject: mwifiex: channel switch handling for station

After receiving channel switch announcement from AP, scan and
association on that channel is blocked for DFS_CHAN_MOVE_TIME
(10 seconds). Hence station will be able to connect to the AP,
once it is moved to new channel.

Subject: sh_eth: remove 'tx_error_check' field of 'struct sh_eth_cpu_data'

The 'tx_error_check' field of 'struct sh_eth_cpu_data' is write-only, so remove
it along with the DEFAULT_TX_ERROR_CHECK macro.

Subject: sh_eth: get R8A7740 Rx descriptor word 0 shift out of #ifdef

The only R8A7740 specific #ifdef hindering  ARM multiplatform build is  left in
sh_eth_rx(): it covers the code shifting Rx buffer descriptor word 0 by 16. Get
rid of the #ifdef by adding 'shift_rd0' field to the  'struct sh_eth_cpu_data',
making the shift dependent on it, and setting it to 1 for the R8A7740 case...

From: Dmitry Kravkov <dmitry@broadcom.com>
Date: Wed, 19 Jun 2013 01:36:04 +0300
Subject: bnx2x: add support for ndo_ll_poll

Adds ndo_ll_poll method and locking for FPs between LL and the napi.

When receiving a packet we use skb_mark_ll to record the napi it came from.
Add each napi to the napi_hash right after netif_napi_add().

Subject: bnx2x: replace mechanism to check for next available packet

Check next packet availability by validating that HW has finished CQE
placement. This saves latency of another dma transaction performed to update
SB indexes.

be_find_vfs() is no longer needed as the common PCI calls provide the same
functionality.

Subject: net: Move MII out from under NET_CORE and hide it

All drivers that select MII also need to select NET_CORE because MII
depends on it.  This is a bit ridiculous because NET_CORE is just a
menu option that doesn't enable any code by itself.

There is also no need for it to be a visible option, since its users
all select it.

Subject: net: Add missing dependencies on NETDEVICES

ETRAX_ETHERNET selects ETHERNET and MII, which depend on NETDEVICES.
I don't think anything should select NETDEVICES, so make it a
dependency.  It also doesn't need to select or depend on ETHERNET,
which has nothing to do with the Ethernet library functions.

BPCTL selects MII, which depends on NETDEVICES.  But everything in the
drivers/staging/silicom directory is related to net devices, so make
NET_VENDOR_SILICOM depend on NETDEVICES and remove the now-redundant
dependencies on NET.

Subject: Bnx2x: remove redundant D0 power state set

Pci_enable_device() will set device power state to D0,
so it's no need to do it again in bnx2x_init_dev().
Also remove redundant PM Cap find code, because pci core
has been saved the pci device pm cap value.

Subject: qlcnic: Secondary unicast MAC address support.

Add support for configuring secondary unicast address which
will use existing HW filters to store all the unicast MAC
addresses and prevent device going into promiscuous mode.

Subject: net: Unmap fragment page once iterator is done

Callers of skb_seq_read() are currently forced to call skb_abort_seq_read()
even when consuming all the data because the last call to skb_seq_read (the
one that returns 0 to indicate the end) fails to unmap the last fragment page.

With this patch callers will be allowed to traverse the SKB data by calling
skb_prepare_seq_read() once and repeatedly calling skb_seq_read() as originally
intended (and documented in the original commit 677e90eda), that is, only call
skb_abort_seq_read() if the sequential read is actually aborted.

Subject: vxlan: move IGMP join/leave to work queue

Do join/leave from work queue to avoid lock inversion problems
between normal socket and RTNL. The code comes out cleaner
as well.

Uses Cong Wang's suggestion to turn refcnt into a real atomic
since now need to handle case where last use of socket is IGMP
worker.

Subject: vxlan: fix race caused by dropping rtnl_unlock

It is possible for two cpu's to race creating vxlan device.
For most cases this is harmless, but the ability to assign "next
avaliable vxlan device" relies on rtnl lock being held across the
whole operation. Therfore two instances of calling:
  ip li add vxlan%d vxlan ...
could collide and create two devices with same name.

To fix this defer creation of socket to a work queue, and
handle possible races there. Introduce a lock to ensure that
changes to vxlan socket hash list is SMP safe.

Subject: vxlan: move cleanup to uninit

Put destruction of per-cpu statistics removal in
ndo_uninit since it is created by ndo_init.
This also avoids any problems that might be cause by destructor
being called after module removed.

Subject: vxlan: convert remotes list to list_rcu

Based on initial work by Mike Rapoport <mike.rapoport@ravellosystems.com>
Use list macros and RCU for tracking multiple remotes.

Note: this code assumes list always has at least one entry,
because delete is not supported.

Subject: ath9k_htc: Add ethtool stats support.

This provides some of the same info found in
the ath9k_htc debugfs through the standard ethtool stats API.

This logic is only supported when ath9k_htc debugfs kernel
feature is enabled, since that is the only time stats
are actually gathered.

Subject: ath9k: fix queue depth accounting in ath_tx_txqaddbuf

ath_tx_txqaddbuf assumes that all the linked buffers in the queue passed
to it are part of the same A-MPDU or MPDU. The CAB queue rework violates
this assumption, which can cause the internal queue depth to go
negative.
Fix this by increasing the counter for all slots of [bf, bf->bf_lastbf]

Subject: cw1200: Fix up a large pile of sparse warnings

Most of these relate to endianness problems, and are purely cosmetic.

But a couple of them were legit -- listen interval parsing and some of
the rate selection code would malfunction on BE systems.

There's still one cosmetic warning remaining, in the (admittedly) ugly
code in cw1200_spi.c.  It's there because the hardware needs 16-bit SPI
transfers, but many SPI controllers only operate 8 bits at a time.

If there's a cleaner way of handling this, I'm all ears.

Subject: rt2x00: read 5GHz TX power values from the correct offset

The current code uses the same index value both
for the channel information array and for the TX
power table. The index starts from 14, however the
index of the TX power table must start from zero.

Fix it, in order to get the correct TX power value
for a given channel.

The changes in rt61pci.c and rt73usb.c are compile
tested only.

Subject: rt2x00: rt2800pci: don't use TXWI_DESC_SIZE directly

Different chipsets may use different TXWI descriptor
size. Instead of using a hardcoded value, use the
'queue->winfo_size' which holds the correct value for
a given device.

Subject: wil6210: set vring index for all descriptors

The vring index (MAC queue id) must be set in all TX descriptors
otherwise HW will fail to release descriptors for a specific vring
(disconnect or vring switch flows).
This is normally occurs when fragmentation required, if vring index
will not be the same for all SKB descriptors HW will fail to flush
this MAC queue.

Subject: wil6210: add HW write-back option in TX descriptor

Map BIT 9 in TX DMA DWARD 0 as HW write back option.
We must turn on this option in the last TX descriptor,
this is required for old HW compatability.
This option indicate to HW that WB is required for this descriptor.

Subject: rtlwifi: rtl8723ae: Fix typo in firmware names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver loads its firmware from files rtlwifi/rtl8723fw*.bin, but the
MODULE_FIRMWARE macros refer to rtlwifi/RTL8723aefw*.bin.

Subject: sfc: Fix EEH with legacy interrupts.

PCI legacy interrupts are level-triggered, and we cannot mask them up
on an isolated device.  Instead, disable the IRQ at the controller
until we have recovered.

Subject: sfc: Do not pass non-TCP packets into GRO code

GRO can handle non-TCP packets and pass them up without coalescing,
but it has to do some extra work to parse the packet which we can
bypass using the hardware parse result.  (This condition yields a
false negative for TCP/IPv6 packets received by Falcon, but its
performance is already poor in that case due to lack of checksum
offload.)

Subject: sfc: Fix IRQ cleanup in case of a probe failure

The lifetime of an irq_cpu_rmap is odd: we have to allocate it before
installing IRQ handlers and free it before removing the IRQ handlers.
As a result of this asymmetry, it was omitted from some failure paths.

On another failure path, we could try to remove IRQ handlers we
had not yet installed.

Move the irq_cpu_rmap allocation and freeing alongside IRQ handler
installation and removal, in efx_nic_{init,fini}_interrupts().
Count the number of IRQ handlers successfully installed and only
remove those on the failure path.

The device::iommu_group field may be set even if no IOMMU is in use.
iommu_present() is still a better indicator, although it doesn't tell
us whether *our* device is affected.

Subject: packet: nlmon: virtual netlink monitoring device for packet sockets

Currently, there is no good possibility to debug netlink traffic that
is being exchanged between kernel and user space. Therefore, this patch
implements a netlink virtual device, so that netlink messages will be
made visible to PF_PACKET sockets. Once there was an approach with a
similar idea [1], but it got forgotten somehow.

I think it makes most sense to accept the "overhead" of an extra netlink
net device over implementing the same functionality from PF_PACKET
sockets once again into netlink sockets. We have BPF filters that can
already be easily applied which even have netlink extensions, we have
RX_RING zero-copy between kernel- and user space that can be reused,
and much more features. So instead of re-implementing all of this, we
simply pass the skb to a given PF_PACKET socket for further analysis.

Another nice benefit that comes from that is that no code needs to be
changed in user space packet analyzers (maybe adding a dissector, but
not more), thus out of the box, we can already capture pcap files of
netlink traffic to debug/troubleshoot netlink problems.

Also thanks goes to Thomas Graf, Flavio Leitner, Jesper Dangaard Brouer.

Subject: iwlwifi: mvm: Change the settings of AP beacon time

In case that an AP/GO interface is started while there is a
station/P2P client associated, need to make sure that the AP/GO
beacon time is far enough from the station's one in oder to allow
the station to receive the DTIM beacons and the following traffic
etc.

To resolve this, when the AP is started, check if there is an
active station interface, and guarantee that the AP/GO TBTT is far
enough from the station one.

Subject: iwlwifi: pcie: rework RX buffer list init and freeing

The PCIe code has an array of buffer descriptors (RXBs) that have pages
and DMA mappings attached. In regular use, the array isn't used and the
buffers are either on the hardware receive queue or the rx_free/rx_used
lists for recycling.

Occasionally, during module unload, we'd see a warning from this:

WARNING: at lib/list_debug.c:32 __list_add+0x91/0xa0()
list_add corruption. prev->next should be next (c31c98cc), but was c31c80bc. (prev=c31c80bc).
Pid: 519, comm: rmmod Tainted: G        W  O 3.4.24-dev #3
Call Trace:
 [<c10335b2>] warn_slowpath_common+0x72/0xa0
 [<c1033683>] warn_slowpath_fmt+0x33/0x40
 [<c12e31d1>] __list_add+0x91/0xa0

 [<fdf2dd7a>] iwl_trans_pcie_free+0x2a/0x90 [iwlwifi]

The reason for this seems to be that in iwl_pcie_rxq_free_rbs() we use
the array to free all buffers (the hardware receive queue isn't in use
any more at this point). The function also adds all buffers to rx_used
because it's also used during initialisation (when no freeing happens.)
This can cause the warning because it may add entries to the list that
are already on it. Luckily, this is harmless because it can only happen
when the entire data structure is freed anyway, since during init both
lists are initialized from scratch.

Disentangle this code and treat init and free separately. During init
we just need to put them onto the list after freeing all buffers (for
switching between 4k/8k buffers); during free no list manipulations
are necessary at all.

Subject: iwlwifi: mvm: Add support for Low Power RX

To improve power consumption in idle associated mode FW may lower
RX power. This low linearity mode is acceptable for listening low rate
RX such as beacons and groupcast. The driver enables LPRX only if PM
is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps.
LPRX RSSI threshold is used to limit a range where LPRX is applied.

Subject: vxlan: fdb: allow specifying multiple destinations for zero MAC

The zero MAC entry in the fdb is used as default destination. With
multiple default destinations it is possible to use vxlan in
environments that disable multicast on the infrastructure level, e.g.
public clouds.

Subject: qeth: change default standard blkt settings for OSA

blkt settings (or LAN idle settings) for an OSA Express card
determine when and how often an OSA Express card tells the
operating system about new incoming packets. The semantic of
these settings has changed starting with OSA Express3. Currently
the qeth standard settings apply to OSA Express2 and older
generations of OSA Express cards, while new generations of OSA
Express cards require extra coding of their reasonable default.

To cover future OSA Express generations the qeth default standard
blkt setting is now the desired setting for OSA generations
starting with OSA Express3, while the fixed set of older OSA
Express cards receives its blkt settings explicitly.

Subject: qeth: Fix crash on initial MTU size change

When the initial MTU size is changed prior to any activity on the device
(e.g. by attaching a z/VM vNIC already configured in Linux to a guestLAN),
we call dev_kfree_skb_irq(NULL) which results in a kernel panic.
Adding a proper check for NULL pointers to address this issue.

Subject: qeth: use default napi weight

Since commit 82dc3c63c692b1e1d59378ecee948ac88e034aad
"net: introduce NAPI_POLL_WEIGHT" network drivers receive a warning
when they use napi weight higher than NAPI_POLL_WEIGHT. This patch
reduces QETH_NAPI_WEIGHT from 128 to 64 (NAPI_POLL_WEIGHT).

Subject: mlx4: allow order-0 memory allocations in RX path

Signed-off-by: Eric Dumazet <edumazet@google.com>

mlx4 exclusively uses order-2 allocations in RX path, which are
likely to fail under memory pressure.

We therefore drop frames more than needed.

This patch tries order-3, order-2, order-1 and finally order-0
allocations to keep good performance, yet allow allocations if/when
memory gets fragmented.

By using larger pages, and avoiding unnecessary get_page()/put_page()
on compound pages, this patch improves performance as well, lowering
false sharing on struct page.

Also use GFP_KERNEL allocations in initialization path, as allocating 12
MB (390 order-3 pages) can easily fail with GFP_ATOMIC.

Subject: net/mlx4_en: Do not query stats when device port is down

There are no counters allocated to the eth device when the port is down, so
this query is meaningless at that time.

It also leads to querying incorrect counters (since the counter_index is not
valid when the device port is down).

Subject: net/mlx4_en: Move register_netdev() to the end of initialization
 function

To avoid a race between the open function and everything that happens after
register_netdev() move it to be the last operation called.

The port vlan table size is 126 (used for IBoE) so after 126 we will
not have space and the user need to see it only in debug print and not
error.

+* Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
+
+Required properties:
+- compatible: Should be "snps,arc-emac"
+- reg: Address and length of the register set for the device
+- interrupts: Should contain the EMAC interrupts
+- clock-frequency: CPU frequency. It is needed to calculate and set polling
+period of EMAC.
+- max-speed: Maximum supported data-rate in Mbit/s. In some HW configurations
+bandwidth of external memory controller might be a limiting factor. That's why
+it's required to specify which data-rate is supported on current SoC or FPGA.
+For example if only 10 Mbit/s is supported (10BASE-T) set "10". If 100 Mbit/s is
+supported (100BASE-TX) set "100".
+- phy: PHY device attached to the EMAC via MDIO bus
+
+Child nodes of the driver are the individual PHY devices connected to the
+MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
+
+Optional properties:
+- mac-address: 6 bytes, mac address
+
+Examples:
+
+	ethernet@c0fc2000 {
+		compatible = "snps,arc-emac";
+		reg = <0xc0fc2000 0x3c>;
+		interrupts = <6>;
+		mac-address = [ 00 11 22 33 44 55 ];
+		clock-frequency = <80000000>;
+		max-speed = <100>;
+		phy = <&phy0>;
+
+		#address-cells = <1>;
+		#size-cells = <0>;
+		phy0: ethernet-phy@0 {
+			reg = <1>;
+		};

From 441ac0fcaadc76ad09771812382345001dd2b813 Mon Sep 17 00:00:00 2001
From: Vlad Yasevich <vyasevic@redhat.com>

Subject: macvtap: Convert to using rtnl lock

Macvtap uses a private lock to protect the relationship between
macvtap_queue and macvlan_dev.  The private lock is not needed
since the relationship is managed by user via open(), release(),
and dellink() calls.  dellink() already happens under rtnl, so
we can safely convert open() and release(), and use it in ioctl()
as well.

Suggested by Eric Dumazet.

Subject: macvtap: Consistently use rcu functions

Currently macvtap uses rcu_bh functions in its
user facing fuction macvtap_get_user() and macvtap_put_user().
However, its packet handlers use normal rcu as the rcu_read_lock()
is taken in netif_receive_skb().  We can safely discontinue
the usage or rcu with bh disabled.

Subject: macvtap: Let TUNSETOFFLOAD actually controll offload features.

When the user issues TUNSETOFFLOAD ioctl, macvtap does not do
anything other then to verify arguments.  This patch adds
functionality to allow users to actually control offload features.
NETIF_F_GSO and NETIF_F_GRO are always on, but the rest of the
features can be controlled.

Subject: macvtap: Perform GSO on forwarding path.

When macvtap forwards skb to its tap, it needs to check
if GSO needs to be performed.  This is sometimes necessary
when the HW device performed GRO, but the guest reading
from the tap does not support it (ex: Windows 7).

This ensures more consistent error values and simplifies error paths.

Subject: bonding: add helper function bond_get_targets_ip(targets, ip)

Add function bond_get_targets_ip(targets, ip) which searches through
targets array of ips (arp_targets) and returns the position of first
match. If ip == 0, returns the first free slot. On failure to find the
ip or free slot, return -1.

Use it to verify if the arp we've received is valid and in sysfs.

v1->v2:
Fix "[2/6] bonding: add helper function bond_get_targets_ip(targets, ip)",
per Nikolay's advice, to verify if source ip != 0.0.0.0, otherwise we might
update 'null' arp_ip_targets' last_rx. Also, address style.

Subject: bonding: don't validate arp if we don't have to

Currently, we validate all the incoming arps if arp_validate not 0.
However, we don't have to validate backup slaves if arp_validate == active
and vice versa, so return early in bond_arp_rcv() in these cases.

It works correctly now because we verify arp_validate in slave_last_rx(),
however we're just doing useless work in bond_arp_rcv().

Subject: bonding: don't trust arp requests unless active slave really works

Currently, if we receive any arp packet on a backup slave in active-backup
mode and arp_validate enabled, we suppose that it's an arp request, swap
source/target ip and try to validate it. This optimization gives us
virtually no downtime in the most common situation (active and backup
slaves are in the same broadcast domain and the active slave failed).

However, if we can't reach the arp_ip_target(s), we end up in an endless
loop of reselecting slaves, because we receive our arp requests, sent by
the active slave, and think that backup slaves are up, thus selecting them
as active and, again, sending arp requests, which fool our backup slaves.

Fix this by not validating the swapped arp packets if the current active
slave didn't receive any arp reply after it was selected as active. This
way we will only accept arp requests if we know that the current active
slave can actually reach arp_ip_target.

v3->v4:
Obey 80 lines and make checkpatch.pl happy, per Sergei's suggestion.

v1->v3:
No change.

Subject: bonding: add an option to fail when any of arp_ip_target is
 inaccessible

Currently, we fail only when all of the ips in arp_ip_target are gone.
However, in some situations we might need to fail if even one host from
arp_ip_target becomes unavailable.

All situations, obviously, rely on the idea that we need *completely*
functional network, with all interfaces/addresses working correctly.

One real world example might be:
vlans on top on bond (hybrid port). If bond and vlans have ips assigned
and we have their peers monitored via arp_ip_target - in case of switch
misconfiguration (trunk/access port), slave driver malfunction or
tagged/untagged traffic dropped on the way - we will be able to switch
to another slave.

Though any other configuration needs that if we need to have access to all
arp_ip_targets.

This patch adds this possibility by adding a new parameter -
arp_all_targets (both as a module parameter and as a sysfs knob). It can be
set to:

	0 or any (the default) - which works exactly as it's working now -
	the slave is up if any of the arp_ip_targets are up.

	1 or all - the slave is up if all of the arp_ip_targets are up.

This parameter can be changed on the fly (via sysfs), and requires the mode
to be active-backup and arp_validate to be enabled (it obeys the
arp_validate config on which slaves to validate).

Internally it's done through:

1) Add target_last_arp_rx[BOND_MAX_ARP_TARGETS] array to slave struct. It's
   an array of jiffies, meaning that slave->target_last_arp_rx[i] is the
   last time we've received arp from bond->params.arp_targets[i] on this
   slave.

2) If we successfully validate an arp from bond->params.arp_targets[i] in
   bond_validate_arp() - update the slave->target_last_arp_rx[i] with the
   current jiffies value.

3) When getting slave's last_rx via slave_last_rx(), we return the oldest
   time when we've received an arp from any address in
   bond->params.arp_targets[].

If the value of arp_all_targets == 0 - we still work the same way as
before.

Also, update the documentation to reflect the new parameter.

v3->v4:
Kill the forgotten rtnl_unlock(), rephrase the documentation part to be
more clear, don't fail setting arp_all_targets if arp_validate is not set -
it has no effect anyway but can be easier to set up. Also, print a warning
if the last arp_ip_target is removed while the arp_interval is on, but not
the arp_validate.

v2->v3:
Use _bh spinlock, remove useless rtnl_lock() and use jiffies for new
arp_ip_target last arp, instead of slave_last_rx(). On bond_enslave(),
use the same initialization value for target_last_arp_rx[] as is used
for the default last_arp_rx, to avoid useless interface flaps.

Also, instead of failing to remove the last arp_ip_target just print a
warning - otherwise it might break existing scripts.

v1->v2:
Correctly handle adding/removing hosts in arp_ip_target - we need to
shift/initialize all slave's target_last_arp_rx. Also, don't fail module
loading on arp_all_targets misconfiguration, just disable it, and some
minor style fixes.

Subject: arc_emac: fix compile-time errors & warnings on PPC64

As reported by "kbuild test robot" there were some errors and warnings
on attempt to build kernel with "make ARCH=powerpc allmodconfig".

And this patch addresses both errors and warnings.
Below is a list of introduced changes:
1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC.
2. Use DMA address instead of "skb->data" as a pointer to data buffer.
This fixed warnings on pointer to int conversion on 64-bit systems.
3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in
the same way they're re-allocated during operation (receiving packets).
So once again DMA address could be used instead of "skb->data".
4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.

Subject: can: flexcan: Use a regulator to control the CAN transceiver

Instead of using a GPIO to turn on/off the CAN transceiver, it is better to
use a regulator as some systems may use a PMIC to power the CAN transceiver.

Subject: rt2x00: rt2800: increase EEPROM_SIZE to 512 bytes

Ralink 3T chipsets are using a different EEPROM
layout than the others. The EEPROM on these devices
contain more data than the others which does not fit
into 272 byte which the rt2800 driver actually uses.

The Ralink reference driver defines EEPROM_SIZE to
512/1024 bytes for PCI/USB devices respectively.

Increase the EEPROM_SIZE constant to 512 bytes, in
order to make room for EEPROM data of 3T devices.

The secondary PAs/LNAs are turned on only for 2T/2R
devices, however these are used for 3T/3R devices as
well. Always turn those on if the device uses more
than one tx/rx chains.

Subject: rt2x00: rt2800lib: turn on tertiary PAs/LNAs for 3T/3R devices

The 3T/3R devices are using the tertiary PAs/LNAs
however those are never turned on. Fix the code to
turn on those on for such devices.

Also modify the code to use switch statements to
improve readability.

Subject: rt2x00: rt2800lib: fix default TX power check for RT55xx

The code writes the default_power2 value into the TX field
of the RFCSR50 register, however the condition in the if
statement uses default_power1. Due to this, wrong TX power
value might be written into the register.

Use the correct value in the condition to fix the issue.

Compile tested only.

Subject: ath10k: fix 5ghz channel definitions

Nonsense channel flags were being set.

Although it doesn't seem this was visible to the
user the patch makes sure that channel
availability won't be crippled in the future if
ath_common behaviour changes.

Subject: ath10k: leave MMIC generation to the HW

Apparently HW doesn't require us to generate MMIC
for TKIP suite.

Each frame was 8 bytes longer than it should be
and some APs would drop frames that exceed 1520
bytes of 802.11 payload. This could be observed
during throughput tests or fragmented IP traffic.

Subject: brcmfmac: simplify transmit path

When getting a transmit packet from the networking layer simply
enqueue the packet unconditional and have it handled by the dequeue
worker. The transfer of the packet to the bus-specific driver part
is now done from one context.

Subject: brcmfmac: add broken scatter-gather DMA support

DMA engine of some old SDIO host controllers require block size alignment for
data length of each scatterlist item. This patch introduces an intermediate
buffer list to support this kind of platform. It decreases the throughput
because of an extra memcpy in critical data path. So don't turn this on unless
it's necessary.

Subject: brcmfmac: tag packet in the netdev transmit callback

Transmit packets needs to be tagged in order to receive a tx status
feedback from the firmware. Determine the tag in the netdev transmit
callback instead of determining the tag just before transfer to the
device. This reduces the number of exception flows and hence makes
the driver code simpler.

Subject: brcmfmac: reduce firmware-signalling locking scope in rx path

In the receive path a spinlock is taken upon parsing the TLV signal
header. This moves to locking to the TLV handling functions where
it protects the data structures.

This is needed so the interface combination can still be
validated when CONFIG_MAC80211_MESH is not enabled.
Otherwise wiphy registration fails.

We have a member called setup_by_slave in struct bonding to denote if the
bond dev has different type than ARPHRD_ETHER, but that is already denoted
in bond's netdev type variable if it was setup by the slave, so use that
instead of the member.

Subject: bonding: remove unnecessary dev_addr_from_first member

In struct bonding there's a member called dev_addr_from_first which is
used to denote when the bond dev should clone the first slave's MAC
address but since we have netdev's addr_assign_type variable that is not
necessary. We clone the first slave's MAC each time we have a random MAC
set to the bond device. This has the nice side-effect of also fixing an
inconsistency - when the MAC address of the bond dev is set after its
creation, but prior to having slaves, it's not kept and the first slave's
MAC is cloned. The only way to keep the MAC was to create the bond device
with the MAC address set (e.g. through ip link). In all cases if the
bond device is left without any slaves - its MAC gets reset to a random
one as before.

Subject: bonding: when cloning a MAC use NET_ADDR_STOLEN

A simple semantic change, when a slave's MAC is cloned by the bond
master then set addr_assign_type to NET_ADDR_STOLEN instead of
NET_ADDR_SET. Also use bond_set_dev_addr() in BOND_FOM_ACTIVE mode
to change the bond's MAC address because the assign_type has to be
set properly.

From 29cc436cb90da4cabf404d8ceedc762fc7387b15 Mon Sep 17 00:00:00 2001
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
Date: Fri, 28 Jun 2013 14:02:54 +0300
Subject: pch_gbe: use managed functions pcim_* and devm_*

This makes the error handling much more simpler than open-coding everything and
in addition makes the probe function smaller an tidier.

Subject: nlmon: fix comparison in nlmon_is_valid_mtu

This patch fixes the following warning introduced in e4fc408e0e99
("packet: nlmon: virtual netlink monitoring device for packet
sockets") reported by Dan Carpenter:

warning: "drivers/net/nlmon.c:31 nlmon_is_valid_mtu()
	 warn: always true condition '(new_mtu <= ((~0 >> 1))) =>
				      (s32min-s32max <= s32max)'"

Thus, we should simply remove the test against INT_MAX. Next to that
we also need to explicitly cast the sizeof() case as the comparison
is type promoted to unsigned long so negative values are then
valid instead of invalid. While at it, this also adds a comment about
Netlink and MTUs.

Subject: net/mlx4_core: Dynamic VST to VST vlan/qos changes

Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.

This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).

To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.

If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

From 0a6eac24583848490e9a9c02daef5e33c997431f Mon Sep 17 00:00:00 2001
From: Rony Efraim <ronye@mellanox.com>
Date: Thu, 27 Jun 2013 19:05:22 +0300
Subject: net/mlx4_core: Add HW enforcement to VF link state

When the firmware supports the UPDATE_QP command, if the VF link is disabled,
block all QPs opened by the VF, by programming the UPDATE_QP command to drop
all RX & TX traffic to/from these QPs. Operates only in VST mode.

Subject: alx: treat flow control correctly in alx_set_pauseparam()

Even when alx_setup_speed_duplex() is called, we still
need to call alx_cfg_mac_flowcontrol() and set hw->flowctrl
if flow control changed.

This was a bug I accidentally introduced while simplifying
the original driver.

Subject: alx: fix MAC address alignment problem

In two places, parts of MAC addresses are used as u32/u16
values. This can cause alignment problems, use put_unaligned
and get_unaligned to fix this.

Subject: alx: fix ethtool support code

A number of places treated features wrongly, listing not-supported
features instead of supported ones. Also, the get_drvinfo ethtool
callback isn't needed, and alx_get_pauseparam can be simplified.

Setup the multicast list of the net_device instead of
clearing it blindly. This restores the multicast groups
in case of a link down/up event or when resuming from
suspend.

Instead of mixing printk and pr_<level> forms,
just use pr_<level>

Miscellaneous changes around these conversions:

Add a missing newline to avoid message interleaving,
coalesce formats, reflow modified lines to 80 columns.

Subject: net: stmmac: fixed enh_desc set always zero

This patch fixed that enh_desc value is always zero.
Due to calling order of stmmac_selec_desc_mode(), enh_desc value is always zero.
Even though mac is set to use enhanced dma descriptor, if enh_desc is zero,
functions related dma descriptor are not working correctly.

Subject: net: qmi_wwan: fixup Sierra Wireless MC8305 entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The MC8305 module got an additional entry added based solely on
information from a Windows driver *.inf file. We now have the
actual descriptor layout from one of these modules, and it
consists of two alternate configurations where cfg #1 is a
normal Gobi 2k layout and cfg #2 is MBIM only, using interface
numbers 5 and 6 for MBIM control and data. The extra Windows
driver entry for interface number 5 was most likely a bug.

Deleting the bogus entry to avoid unnecessary qmi_wwan probe
failures when using the MBIM configuration.

Note: a follow-up patch was posted to the linux-usb mailing list, to prevent
the option driver from binding to the device's QMI interface, making it
unusable.

Subject: bnx2x: remove zeroing of dump data buffer

There is no need to initialize the dump data with zeros.
data is allocated with vzalloc, so it's already zero-filled.

More importantly, the memset is harmful, because dump->len (the length
requested by userspace) can be bigger than the allocated buffer (whose
size is determined by asking the driver's .get_dump_flag method).

Subject: bnx2x: fix dump flag handling

bnx2x interprets the dump flag as an index of a register preset.
It is important to validate the index to avoid out of bounds
memory accesses.

Subject: bnx2x: fill in sane dump flag information

bnx2x did not set dump->version in its .get_dump_flag() method.
Let's set it to BNX2X_DUMP_VERSION. It's not a particularly nice
number (0x50acff01 currently), but at least it's something
deterministic.

dump->flag should report the value previously set using ethtool -W.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some Icera based Huawei modems handled by this driver are not
completely CDC ECM compliant, using the same USB interface for both
control and data. The CDC functional descriptors include a Union
naming this interface as both master and slave, so it is supportable
by relaxing the descriptor parsing in case these interfaces are
identical.

This has been tested on a Huawei K3806 and verified to add support
for that device.

It appears that t3_resume_ports() is called with the rtnl_lock held from
the fatal error task but not from the PCI error callbacks. This fixes it.

From 83d7af64ac9eaf4f4db7228677bc25f23c383790 Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Tue, 2 Jul 2013 14:12:36 +0200
Subject: stmmac: dity-up and rework the driver debug levels

Prior this patch, the internal debugging was based on ifdef
and also some printk were useless because many info are exposed
via ethtool.
This patch remove all the ifdef defines and now we only use
netif_msg_XXX levels.

Subject: alx: remove WoL support

Unfortunately, WoL is broken and the system will immediately
resume after suspending, and I can't seem to figure out why.
Remove WoL support until the issue can be found.

Subject: dt:net:stmmac: Allocate platform data only if its NULL.

In some DT use-cases platform data might be already allocated and passed
via AUXDATA. These are the cases where machine level code populates few
callbacks in the platform data.

This patch adds check and reuses platform_data if its valid, before
allocating a new one.

This patch adds phy reset callback support for stmmac driver via device

define the reset signal via gpio.

With this patch users can conveniently pass reset gpio number with pre,
pulse and post delay in micro secs via DTs.

Subject: sfc: Fix memory leak when discarding scattered packets

Commit 2768935a4660 ('sfc: reuse pages to avoid DMA mapping/unmapping
costs') did not fully take account of DMA scattering which was
introduced immediately before.  If a received packet is invalid and
must be discarded, we only drop a reference to the first buffer's
page, but we need to drop a reference for each buffer the packet
used.

I think this bug was missed partly because efx_recycle_rx_buffers()

change the state of buffers, but only prepares the underlying pages
for recycling.  Rename it accordingly.

Subject: virtio: support unlocked queue poll

This adds a way to check ring empty state after enable_cb outside any
locks. Will be used by virtio_net.

Note: there's room for more optimization: caller is likely to have a
memory barrier already, which means we might be able to get rid of a
barrier here.  Deferring this optimization until we do some
benchmarking.

Subject: virtio_net: fix race in RX VQ processing

virtio net called virtqueue_enable_cq on RX path after napi_complete, so
with NAPI_STATE_SCHED clear - outside the implicit napi lock.
This violates the requirement to synchronize virtqueue_enable_cq wrt
virtqueue_add_buf.  In particular, used event can move backwards,
causing us to lose interrupts.
In a debug build, this can trigger panic within START_USE.

Jason Wang reports that he can trigger the races artificially,
by adding udelay() in virtqueue_enable_cb() after virtio_mb().

However, we must call napi_complete to clear NAPI_STATE_SCHED before
polling the virtqueue for used buffers, otherwise napi_schedule_prep in
a callback will fail, causing us to lose RX events.

To fix, call virtqueue_enable_cb_prepare with NAPI_STATE_SCHED
set (under napi lock), later call virtqueue_poll with
NAPI_STATE_SCHED clear (outside the lock).

Subject: net: mv643xx_eth: do not use port number as platform device id

The port number is only local to the ethernet block, not global, so
there can be two ethernet blocks both using the same port, like
kirkwood with both using port 0.

Fix this by using the array index offset for the allocated platform
devices as the id.

Subject: vhost-net: fix use-after-free in vhost_net_flush

vhost_net_ubuf_put_and_wait has a confusing name:
it will actually also free it's argument.
Thus since commit 1280c27f8e29acf4af2da914e80ec27c3dbd5c01
    "vhost-net: flush outstanding DMAs on memory change"
vhost_net_flush tries to use the argument after passing it
to vhost_net_ubuf_put_and_wait, this results
in use after free.
To fix, don't free the argument in vhost_net_ubuf_put_and_wait,
add an new API for callers that want to free ubufs.

rtnl_is_locked() doesn't check who holds this lock, it just tells that it's
locked right now. if caif::ldisc_close really can be called under rtrnl_lock
then it should release net device in other context because there is no way
to grab rtnl_lock without deadlock.

This patch adds work which releases these devices. Also this patch fixes calling
dev_close/unregister_netdevice without rtnl_lock from caif_ser_exit().
