An HDLC device can change type when the protocol driver is changed.
Calling the notifier change allows potential users of the interface
know about this planned change, and even block it. After the change
has occurred, send a second notification to users can evaluate the new
device type etc.

This is the last shoot of this series.
After I removing all directly reference of netdev->priv, I am killing
"priv" of "struct net_device" and fixing relative comments/docs.
Anyone will not be allowed to reference netdev->priv directly.
If you want to reference the memory of private data, use netdev_priv()
instead.
If the private data is not allocted when alloc_netdev(), use
netdev->ml_priv to point that memory after you creating that private
data.

For killing directly reference of netdev->priv, use netdev->ml_priv to replace it.
Because the private pvc data comes from add_pvc() and can't be allocated in
alloc_netdev().

For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can
later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.
This one touches just the most simple case, next will handle the slightly more
"complex" cases.

This patch enables building of individual WAN protocol support
routines (parts of generic HDLC) as separate modules.
All protocol-private definitions are moved from hdlc.h file
to protocol drivers. User-space interface and interface
between generic HDLC and underlying low-level HDLC drivers
are unchanged.

This patch converts generic HDLC (and WAN drivers using it) from

David Boggs noticed that register_hdlc_device() no longer needs
to call dev_alloc_name() as it's called by register_netdev().
register_hdlc_device() is currently equivalent to register_netdev().
hdlc_setup() is now EXPORTed as per David's request.

The attached patch updates generic HDLC to version 1.18.
FR Cisco LMI production-tested. Please apply to Linux 2.6. Thanks.
Changes:
- doc updates
- added Cisco LMI support to Frame-Relay code
- cleaned hdlc_fr.c a bit, removed some orphaned #defines etc.
- fixed a problem with non-functional LMI in FR DCE mode.
- changed diagnostic messages to better conform to FR standards
- all protocols: information about carrier changes (DCD line) is now
printed to kernel logs.

The attached patch updates generic HDLC:
- fixed some carrier-related problems (Cisco HDLC and FR links could
report valid link when no carrier was detected at startup).
- fixed kbuild problems with wanxl firmware (building kernel in separate
tree). $(src)/wanxlfw.inc is now wanxlfw.inc_shipped.

Now we can kill the embedding of net_device into hdlc_device. Indeed,
all instances of hdlc_device are created by alloc_hdlcdev() and nothing
uses hdlc->netdev directly. So we can
* remove hdlc->netdev
* have alloc_hdlcdev() implemented via alloc_netdev() with the rest
of hdlc_device as private part of net_device.
* replace free_hdlcdev() with free_netdev().
* have dev_to_hdlc(dev) simply return netdev_priv(dev).
|
|
No more users, we may remove it.
|

New field in hdlc_device: void *priv;
New helpers:
struct net_device *alloc_hdlcdev(priv) allocates hdlc, sets ->priv and
returns pointer to hdlc->netdev
free_hdlcdev(dev) takes such pointer and frees its hdlc.
wanxl switched to use of those; instead of embedding hdlc into card->ports[]
we allocate it separately right after card had been allocated and store pointer
to hdlc->netdev in card->ports[]->dev. Freeing is done just before freeing
card. Pointer back to card->ports[] is stored in hdlc->priv. port_to_dev()
and dev_to_port() rewritten in the obvious way; by now the rest of driver
doesn't care whether hdlc is embedded or not - everything uses port_to_dev()
and dev_to_port().
That killed embedded hdlc replacing it with pointer to net_device. Fairly
similar work will be done in the next few patches for other drivers.
Additionally, setup-after-register and free_irq()-before-unregister races
had been fixed.
|
|
register_hdlc_device()/unregister_hdlc_device() switched to net_device.
Now all remaining callers of hdlc_to_dev() are isolated and we can
start killing them.
|
|
New inlined helper - hdlc_stats(). A lot of places had it spelled out;
replaced with calls.
|
|
Switched remaining ioctls to net_device, killed a bunch of hdlc_to_dev()
and killed hdlc_to_name().
|
|
|
|
|
|
|

Eliminated a bunch of ->netdev and hdlc_to_dev() uses.

Beginning of hdlc fixes. hdlc_open() switched from hdlc_device to net_device.

From: Krzysztof Halasa <khc@pm.waw.pl>
The following patch upgrades generic HDLC to support "new" protocol
handlers.
|
|
This updates generic HDLC from 1.14 to 1.15.
- fix a kernel panic caused by a recent change to unregister_netdevice()
(struct net_device * can't be kfreed before rtnl_unlock())
- adds carrier_* support - hw drivers report DCD status and higher level
protocols use that info, and do netif_carrier_{on,off}() according to
DCD and (Cisco and FR) link management status.
- moves Frame-Relay constants etc. from include/linux/hdlc.h to hdlc_fr.c.
They are internal FR things and are not needed in the global header.
- protocol hooks are slighty changed to allow zeroing (memset).
- removes CONFIG_HDLC_DEBUG_* variables. Users tend to make very wrong
use of them. Now setting them requires changing .c #define. Anyway they
are development-only things.
- misc style corrections etc.
|

This version fixes:
- missing rtnl_lock()/rtnl_unload() bug on unregister_hdlc_device
- N2, C101: interrupt handler now works under high IRQ load from other
devices (with previous versions, the IRQ processing for the card could
sometimes stop after reaching "work limit")
This is production-tested on devices I have access to (N2, C101, PC300,
PCI200SYN).

device and protocol attach/detach support.
Overall, this is in preparation for update of HDLC API
|
|
New file and directory include/linux/hdlc/ioctl.h, containing
only WAN ioctl-related definitions.
Update include/linux/if.h to reference these structures, providing
us with complete type safety, including through ioctls.
|
|
s/SIOCDEVICE/SIOCWANDEV/
|
|
Add new HDLC interface, split up huge hdlc.c driver into
multiple files based on hardware type. Convert WAN drivers
to new interface.
