netdev/phy: Make get_phy_id() static and quit EXPORTing it.

2012-05-16T04:59:12Z

This function is only referenced from within phy_device.c, so there is no reason to export it. In fact, we can make it static. Signed-off-by: David Daney Acked-by: Paul Gortmaker Signed-off-by: David S. Miller

ethtool: Introduce a method for getting time stamping capabilities.

2012-04-04T09:28:45Z

This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING capabilities of a network interface. In addition, user space programs can use this ioctl to discover the PTP Hardware Clock (PHC) device associated with the interface. Since software receive time stamps are handled by the stack, the generic ethtool code can answer the query correctly in case the MAC or PHY drivers lack special time stamping features.

device.h: audit and cleanup users in main include dir

2012-03-16T14:38:24Z

The header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker

phylib: introduce mdiobus_alloc_size()

2012-01-12T23:23:04Z

Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc(). Most callers of mdiobus_alloc() also allocate a private data structure, and then manually point bus->priv to this object. mdiobus_alloc_size() combines the two operations into one, which simplifies memory management. The original mdiobus_alloc() now just calls mdiobus_alloc_size(0). Signed-off-by: Timur Tabi Signed-off-by: David S. Miller

net: hold sock reference while processing tx timestamps

2011-10-24T06:54:50Z

The pair of functions, * skb_clone_tx_timestamp() * skb_complete_tx_timestamp() were designed to allow timestamping in PHY devices. The first function, called during the MAC driver's hard_xmit method, identifies PTP protocol packets, clones them, and gives them to the PHY device driver. The PHY driver may hold onto the packet and deliver it at a later time using the second function, which adds the packet to the socket's error queue. As pointed out by Johannes, nothing prevents the socket from disappearing while the cloned packet is sitting in the PHY driver awaiting a timestamp. This patch fixes the issue by taking a reference on the socket for each such packet. In addition, the comments regarding the usage of these function are expanded to highlight the rule that PHY drivers must use skb_complete_tx_timestamp() to release the packet, in order to release the socket reference, too. These functions first appeared in v2.6.36. Reported-by: Johannes Berg Signed-off-by: Richard Cochran Cc: Signed-off-by: Eric Dumazet Reviewed-by: Johannes Berg Signed-off-by: David S. Miller

net: ibm_newemac: convert it to use of_get_phy_mode

2011-07-27T01:31:02Z

The patch extends 'enum phy_interface_t' and of_get_phy_mode a little bit with PHY_INTERFACE_MODE_NA and PHY_INTERFACE_MODE_SMII added, and then converts ibm_newemac net driver to use of_get_phy_mode getting phy mode from device tree. It also resolves the namespace conflict on phy_read/write between common mdiobus interface and ibm_newemac private one. Signed-off-by: Shawn Guo Cc: David S.

net: support time stamping in phy devices.

2010-07-19T02:15:26Z

This patch adds a new networking option to allow hardware time stamps from PHY devices. When enabled, likely candidates among incoming and outgoing network packets are offered to the PHY driver for possible time stamping. When accepted by the PHY driver, incoming packets are deferred for later delivery by the driver. The patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl and callbacks for transmit and receive time stamping. Drivers may optionally implement these functions.
