2014-11-12enic: fix work done in tx napi_pollGovindarajulu Varadarajan
With the commit d75b1ade567 ("net: less interrupt masking in NAPI") napi repoll is done only when work_done == budget. In tx napi poll we always return 0. So tx napi is not called again and we do not clean up the tx ring. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-11-12net: ptp: fix time stamp matching logic for VLAN packets.Richard Cochran
Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the code in two drivers that matches time stamps with PTP frames, with the goal of allowing VLAN tagged PTP packets to receive hardware time stamps. However, that commit failed to account for the VLAN header when parsing IPv4 packets. This patch fixes those two drivers to correctly match VLAN tagged IPv4/UDP PTP messages with their time stamps. This patch should also be applied to v3.17. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-11-11net: bcmgenet: apply MII configuration in bcmgenet_open()Florian Fainelli
In case an interface has been brought down before entering S3, and then brought up out of S3, all the initialization done during bcmgenet_probe() by bcmgenet_mii_init() calling bcmgenet_mii_config() is just lost since register contents are restored to their reset values. Re-apply this configuration anytime we call bcmgenet_open() to make sure our port multiplexer is properly configured to match the PHY interface. Since we are now calling bcmgenet_mii_config() everytime bcmgenet_open() is called, make sure we only print the message during initialization time not to pollute the console.

This fixes an issue where a network interface was suspended prior to a system suspend/resume cycle and would then be resumed as part of mdio_bus_resume(), since the GENET interface clocks would have been disabled, this basically resulted in bus errors to appear since we are invoking the GENET driver adjust_link() callback.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-11-11 This series contains updates to i40e, i40evf and ixgbe. Kamil updated the i40e and i40evf driver to poll the firmware slower since we were polling faster than the firmware could respond. Shannon updates i40e to add a check to keep the service_task from running the periodic tasks more than once per second, while still allowing quick action to service the events. Jesse cleans up the throttle rate code by fixing the minimum interrupt throttle rate and removing some unused defines. Mitch makes the early init admin queue message receive code more robust by handling messages in a loop and ignoring those that we are not interested in. This also gets rid of some scary log messages that really do not indicate a problem. Don provides several ixgbe patches, first fixes an issue with x540 completion timeout where on topologies including few levels of PCIe switching for x540 can run into an unexpected completion error. Cleans up the functionality in ixgbe_ndo_set_vf_vlan() in preparation for future work. Adds support for x550 MAC's to the driver. v2: - Remove code comment in patch 01 of the series, based on feedback from David Liaght - Updated the "goto" to "break" statements in patch 06 of the series, based on feedback from Sergei Shtylyov - Initialized the variable err due to the possibility of use before being assigned a value in patch 07 of the series - Added patch "ixgbe: add helper function for setting RSS key in preparation of X550" since it is needed for the addition of X550 MAC support ==================== Signed-off-by: David S.

2014-11-11i40e: don't do link_status or stats collection on every ARQShannon Nelson
The ARQ events cause a service_task execution, and we do a link_status check and full stats gathering for each service_task. However, when there are a lot of ARQ events, such as when doing an NVM update, we end up doing 10's if not 100's of these per second, thereby heavily abusing the PCI bus and especially the Firmware. This patch adds a check to keep the service_task from running these periodic tasks more than once per second, while still allowing quick action to service the events.

2014-11-10mlx4: use napi_complete_done()Eric Dumazet
To enable gro_flush_timeout, a driver has to use napi_complete_done() instead of napi_complete(). Tested: Ran 200 netperf TCP_STREAM from A to B (10Gbe mlx4 link, 8 RX queues) Without this feature, we send back about 305,000 ACK per second. GRO aggregation ratio is low (811/305 = 2.65 segments per GRO packet) Setting a timer of 2000 nsec is enough to increase GRO packet sizes and reduce number of ACK packets. (811/19.2 = 42) Receiver performs less calls to upper stacks, less wakes up. This also reduces cpu usage on the sender, as it receives less ACK packets. Note that reducing number of wakes up increases cpu efficiency, but can decrease QPS, as applications wont have the chance to warmup cpu caches doing a partial read of RPC requests/answers if they fit in one skb.

2014-11-07net: fec: fix regression on i.MX28 introduced by rx_copybreak supportLothar Waßmann
commit 1b7bde6d659d ("net: fec: implement rx_copybreak to improve rx performance") introduced a regression for i.MX28. The swap_buffer() function doing the endian conversion of the received data on i.MX28 may access memory beyond the actual packet size in the DMA buffer. fec_enet_copybreak() does not copy those bytes, so that the last bytes of a packet may be filled with invalid data after swapping. This will likely lead to checksum errors on received packets. E.g. when trying to mount an NFS rootfs: UDP: bad checksum. From 192.168.1.225:111 to 192.168.100.73:44662 ulen 36 Do the byte swapping and copying to the new skb in one go if necessary.

2014-11-06amd-xgbe: Check for complete packet on skb allocation errorLendacky, Thomas
If the skb allocation fails during receive processing, the driver would continue reading descriptors without first determining if there were any more descriptors for the current packet. Update the code to check whether more descriptors are associated with the current packet or whether to move on to the next descriptor as a new packet.

2014-11-06amd-xgbe: Free channel/ring structures laterLendacky, Thomas
The channel structure is freed before freeing the per channel interrupts resulting in a kernel oops. Move the call to free the channel structure to after the freeing of the per channel interrupts.
