====================
Intel Wired LAN Driver Updates

This series contains updates to i40e only.

Majority of this series contains patches from Greg and Mitch to fix
up or add functionality to the PF/VF driver interactions.  Notably,
a fix for SR-IOV VF port VLAN which resolved the problem of port VLAN
configurations not being persistent across VF driver loads and unloads
and enable/disable of the feature.  Also do not enable the default port
on the VEB, which is designed only to bridge the PF to an Open vSwitch
or bridge.  Another fix to resolve a possible memory corruption
condition where ARQ messages are written to random memory locations.
Fix a problem where the 'ip link show' command would display stale
link address information after the link address was set via the 'ip
link set' command.

Anjali provides several patches, one which saves information that can
be used while cleaning the Tx ring and useful in detecting Tx hangs.
Then provides a fixes to the admin queue shutdown function to ensure
we are shutting down the queue in the shutdown path and ensure ASQ is
alive before issuing the admin queue command.

Shannon provides a fix for get/update vsi params where the incorrect
struct was being used.
