2013-01-18net: fec: enable pause frame to improve rx prefomance for 1G networkFrank Li
The limition of imx6 internal bus cause fec can't achieve 1G perfomance. There will be many packages lost because FIFO over run. This patch enable pause frame flow control.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

2012-11-09gianfar: ethernet vanishes after restoring from hibernationWang Dongsheng
If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.

2012-10-07net: remove skb recyclingEric Dumazet
Over time, skb recycling infrastructure got litle interest and many bugs. Generic rx path skb allocation is now using page fragments for efficient GRO / TCP coalescing, and recyling a tx skb for rx path is not worth the pain. Last identified bug is that fat skbs can be recycled and it can endup using high order pages after few iterations. With help from Maxime Bizon, who pointed out that commit 87151b8689d (net: allow pskb_expand_head() to get maximum tailroom) introduced this regression for recycled skbs. Instead of fixing this bug, lets remove skb recycling.

2012-09-24gianfar: Change default HW Tx queue scheduling modeClaudiu Manoil
This is primarily to address transmission timeout occurrences, when multiple H/W Tx queues are being used concurrently. Because in the priority scheduling mode the controller does not service the Tx queues equally (but in ascending index order), Tx timeouts are being triggered rightaway for a basic test with multiple simultaneous connections like: iperf -c <server_ip> -n 100M -P 8 resulting in kernel trace: NETDEV WATCHDOG: eth1 (fsl-gianfar): transmit queue <X> timed out ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 ... and controller reset during intense traffic, and possibly further complications. This patch changes the default H/W Tx scheduling setting (TXSCHED) for multi-queue devices, from priority scheduling mode to a weighted round robin mode with equal weights for all H/W Tx queues, and addresses the issue above.

2012-08-30net/fsl_pq_mdio: streamline probing of MDIO nodesTimur Tabi
Make the device tree probe function more data-driven, so that it no longer searches the 'compatible' property more than once. The of_device_id[] array allows for per-entry private data, so we use that to store details about each type of node that the driver supports. This removes the need to check the 'compatible' property inside the probe function. The driver supports four types on MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) Gianfar, eTSEC2, and QE have different mappings for the TBIPA register, which is needed to initialize the TBI PHY. In addition, the QE needs a special hack because of the way the device tree is ordered. All of this information is encapsulated in the fsl_pq_mdio_data structure, so when an MDIO node is probed, per-device data and functions are used to determine how to initialize the device.

The correct behavior is to program the interrupt coalescing regs (RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing" flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue then the corresponding coalescing register should be cleared. This behavior is correctly implemented for the single-queue mode (SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE). This fixes the later case.

For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p A function in atl1e_main.c was passed a const pointer when it actually modified elements of the structure. Change the argument to a non-const pointer. A function in stmmac needed a __force to avoid a sparse warning. Added it. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
