git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-24 This series contains updates to i40e and i40evf. Greg provides a patch to stop the VF device after setting its MAC address. This is due to if the host VMM administrator has changed the VF device's MAC address then the i40e driver needs to halt the VF device so that the administrator will be forced to reload the VF driver so that the VF driver will start using the newly assigned MAC address. Shannon provides several patches for i40e, first makes prep_for_test() a void function since the return value was being ignored for the most part by all its callers. Adds a log warning when the firmware's API minor/major number is not what we expect to assist the user by informing them they may need to update their NVM or SW. Cleans up a stray print message so that it is similar to other print messages. Ensures to set the WoL flag when setting LAA and allow the user to set LAA again. So do not short-circuit the LAA assignment when the driver thinks it has already been done as it is possible that the user might want to force the address setting again. Provides a couple more LAA fixes to ensure the LAA gets restored after resets. Neerav provides a patch for i40e to add a PF reset when a malicious driver event for the PF occurs. As per the specification when the PF driver receives a malicious driver event the queue that caused the event is already stopped and it is expected that the function that owns the queue will reset the queue, but in some cases it may not be possible to determine the queue, so it is suggested to reset the whole function. Carolyn fixes ethtool coalesce settings to allow 0 as a disable value and adds message to user about invalid values. Jesse removes a reserved type which was not removed from the code. Catherine provides a patch to add the ability to enable/disable link from set_link)restart_an() which will make it easy to toggle link without calling set_phy_config() when no other link settings need to change. Anjali provides a patch to ensure we do a PF reset on Tx hang and that way we avoid any Malicious Driver Detect (MDD) events because of a Tx queue disable failure. v2: - fixed the un-needed return in patch 2 based on feedback from Sergei Shtylyov - added punctuation to print statements and code comment based on feedback from Sergei Shtylyov ==================== Signed-off-by: David S.

2014-06-24i40e: Bypass timeout recovery level 0 so as to not cause MDDAnjali Singhai Jain1-1/+3
When a Tx hang happens, usually the Tx queue disable fails. At this point if we try to recover by a VSI reinit the HW gets unhappy and we get a Malicious Driver Detect (MDD) event. HW expects a PF reset if a queue disable fails, if we don't do a PF reset and restart the queue we get an MDD. This patch makes sure we do a PF reset on Tx hang and that way we avoid any MDD because of Tx queue disable failure.

2014-06-23enic: Add Accelerated RFS supportGovindarajulu Varadarajan6-0/+279
This patch adds supports for Accelerated Receive Flow Steering. When the desired rx is different from current rq, for a flow, kernel calls the driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP hardware filter. Driver registers a timer function enic_flow_may_expire. This function is called every HZ/4 seconds. In this function we check if the added filter has expired by calling rps_may_expire_flow(). If the flow has expired, it removes the hw filter. As of now adaptor supports only IPv4 - TCP/UDP filters. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.

Anjali provides an update to the registers to handle the updates from the hardware. Also provides a fix so that we do not try to access the rings through the qvectors at the time of freeing the qvectors. Jesse provides a workaround for some older NVM versions where the NVM was not filling in the GLQF_HKEY register, so made sure that the critical register is initialized. Michal provides a fix to reset the head and tail on admin queue initialization where head and tail are not reset by the hardware. Neerav adds a helper routine that would wait for the Rx/Tx queue to reach the enable or disable state that is requested. Also provides a fix to the debugfs command "lldp get remote" which was dumping the local LLDPDU instead of the peer's LLDPDU. Fixed a bug when all the Tx hang recovery mechanisms have failed and the driver tries to bring down the interface in the interrupt context. Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats when the PF stats are cleared. Also cleans the service tasks so that they do not run while a reset is in progress.
