Aaron Brown says: ==================== Intel Wired LAN Driver Updates This series contains updates to the i40e and i40evf drivers. Vasu adds FCOE support, build options and a documentation pointer to i40e. Shannon exposes a Firmware API request used to do register writes on the driver's behalf and disables local loopback on VMDQ VSI in order to stop the VEB from echoing the VMDQ packets back at the VSI. Ashish corrects the vf_id offset for virtchnl messages in the case of multiple PFs, removes support for vf unicast promiscuos mode to disallow VFs from receiving traffic intended for another VF, updates the vfr_stat state check to handle the existing and future mechanism and adds an adapter state check to prevent re-arming the watchdog timer after i40evf_remove has been called and the timer has been deleted. Serey fixes an issue where a guest OS would panic when removing the vf driver while the device is being reset due to an attempt to clean a non initialized mac_filter_list. Akeem makes a minor comment change. Jessie changes an instance of sprintf to snprintf that was missed when the driver was converted to use snprintf everywhere. Mitch plugs a few memory leaks. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Removing VF driver during device still in reset caused guest OS panic. in the i40evf_remove(), we're trying to clean mac_filter_list which has not been initialized since the device is still stuck at the reset. The change is to initialize the filter_list before setting any task. Change-ID: I8b59df7384416c7e6f2d264b598f447e1c2c92b0 Signed-off-by:

If the driver is loaded and then unloaded before the interface is brought up, then it will allocate a MAC filter entry and never free it. To fix this, on unload, run through the mac filter list and free all the entries. We also do this during reset recovery when the driver cannot contact the PF and needs to shut down completely.

Fix a memory leak. Driver was allocating memory for queue vectors on init but not freeing them on shutdown. These need to be freed at two different times: during module unload, and during reset recovery when the driver cannot contact the PF driver and needs to give up.

Lendacky, Thomas authored
The current time range waiting for Rx/Tx to become ready can sometimes be too short if a connection is not present. Increase the number of retries and the sleep to give a bit more time. Also, change level of the message issued from _err to _dbg if Rx/Tx do not become ready since the underlying logic will function as if no link is established and retry eventually. Signed-off-by:
