2014-11-06amd-xgbe: Provide support for receive side scalingLendacky, Thomas5-2/+233
This patch provides support for receive side scaling (RSS). RSS allows for spreading incoming network packets across the Rx queues.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-11-03 This series contains updates to i40e and i40evf. Akeem adds a check for i40e so that flow director flush and reinit are not done when flow director is not enabled. Mitch fixes the i40evf driver to properly handle multiple admin queue messages, by reinit the msg_size field each time we go through the loop. Without this, we may receive truncated messages due to the firmware thinking we have insufficient buffer size. Also fixes the link checking logic to only check the carrier state if the interface is actually open, which allows link changes to be reported correctly without spamming the VFs. Updates i40e to inset the VSI ID in the QTX_CTL register when configuring queues for VMDq VSIs. Paul adds support for 10G-base-T in i40evf. Jesse fixes i40e where the call to irq_dynamic_disable() was turning off the interrupt completely when trying to set ITR to 0 (for lowest moderation). Shannon removes debugfs dump stats function, since it was not being kept up-to-date and was redundant with the ethtool output. Also, scales back the LAN MSIx usage to force queue/vector sharing and leave some vectors for Flow Director, VMDq, etc. when there are more cores than vectors available to the PF. Cleans up the error reporting for get_lump() resource tracking errors. Also adds a check for the debug module parameter earlier to be able to catch the early configuration phase admin queue messages. ==================== Signed-off-by: David S.

2014-11-03net/mlx4_en: Remove RX buffers alignment to IP_ALIGNIdo Shamay2-13/+4
When IP_ALIGN has a non zero value, hardware will write to a non aligned address. The only reader from this address is when copying the header from the first frag into the linear buffer (further access to the IP address will be from the linear buffer, in which the headers are aligned). Since the penalty of non align access by the hardware is greater than the software memcpy, changing the frag_align to always be 0.

2014-10-31net/mlx4_en: Don't attempt to TX offload the outer UDP checksum for VXLANOr Gerlitz1-2/+5
For VXLAN/NVGRE encapsulation, the current HW doesn't support offloading both the outer UDP TX checksum and the inner TCP/UDP TX checksum. The driver doesn't advertize SKB_GSO_UDP_TUNNEL_CSUM, however we are wrongly telling the HW to offload the outer UDP checksum for encapsulated packets, fix that.

Francesco Ruggeri fixes an issue with e1000 where in a VM the driver did not support unicast filtering. Roman Gushchin fixes an issue with igb where the driver was re-using mapped pages so that packets were still getting dropped even if all the memory issues are gone and there is free memory. Junwei Zhang found where in the ixgbe_clean_rx_ring() we were repeating the assignment of NULL to the receive buffer skb and fixes it. Emil fixes a race condition between setup_link and SFP detection routine in the watchdog when setting the advertised speed. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
