2012-11-09gianfar: ethernet vanishes after restoring from hibernationWang Dongsheng1-1/+4
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.

2012-11-09gianfar: Fix alloc_skb_resources on -ENOMEM cleanup pathClaudiu Manoil1-6/+8
Should gfar_init_bds() return with -ENOMEM inside gfar_alloc_skb_resources(), free_skb_resources() will be called twice in a row on the "cleanup" path, leading to duplicate kfree() calls for rx_|tx_queue->rx_|tx_skbuff resulting in segmentation fault. This patch prevents the segmentation fault to happen in the future (rx_|tx_sbkbuff set to NULL), and corrects the error path handling for gfar_init_bds().

2012-11-07bnx2x: Support loading cnic resources at run-timeMerav Sicron12-565/+1084
This patch replaces the BCM_CNIC define with a flag which can change at run-time and which does not use the CONFIG_CNIC kconfig option.

2012-11-07mlx4: change TX coalescing defaultsEric Dumazet2-2/+2
mlx4 currently uses a too high tx coalescing setting, deferring TX completion interrupts by up to 128 us. With the recent skb_orphan() removal in commit 8112ec3b872, performance of a single TCP flow is capped to ~4 Gbps, unless we increase tcp_limit_output_bytes. I suggest using 16 us instead of 128 us, allowing a finer control. Performance of a single TCP flow is restored to previous levels, while keeping TCP small queues fully enabled with default sysctl. This patch is also a BQL prereq.

2012-11-07net: calxedaxgmac: ip align receive buffersRob Herring1-5/+6
On gcc 4.7, we will get alignment traps in the ip stack if we don't align the ip headers on receive. The h/w can support this, so use ip aligned allocations. Cut down the unnecessary padding on the allocation. The buffer can start on any byte alignment, but the size including the begining offset must be 8 byte aligned. So the h/w buffer size must include the NET_IP_ALIGN offset. Thanks to Eric Dumazet for the initial patch highlighting the padding issues.

2012-11-07net: calxedaxgmac: use raw i/o accessors in rx and tx pathsRob Herring1-6/+6

2012-11-03macb: Keep driver's speed/duplex in sync with actual NCFGRVitalii Demianets1-0/+2
When underlying phy driver restores its state very fast after being brought down and up so that macb driver function macb_handle_link_change() was never called with link state "down", driver's internal representation of phy speed and duplex (bp->speed and bp->duplex) didn't change. So, macb driver sees no reason to perform actual write to the NCFGR register, although the speed and duplex settings in that register were reset when interface was brought down and up. In that case actual phy speed and duplex differ from NCFGR settings. The patch fixes that by keeping internal driver representation of speed and duplex in sync with actual content of NCFGR.
