====================
100GbE Intel Wired LAN Driver Updates 2019-03-22

This series contains updates to ice driver only.

Akeem enables MAC anti-spoofing by default when a new VSI is being
created.  Fixes an issue when reclaiming VF resources back to the pool
after reset, by freeing VF resources separately using the first VF
vector index to traverse the list, instead of starting at the last
assigned vectors list.  Added support for VF & PF promiscuous mode in
the ice driver.  Fixed the PF driver from letting the VF know it is "not
trusted" when it attempts to add more than its permitted additional MAC
addresses.  Altered how the driver gets the VF VSIs instances, instead
of using the mailbox messages to retrieve VSIs, get it directly via the
VF object in the PF data structure.

Bruce fixes return values to resolve static analysis warnings.  Made
whitespace changes to increase readability and reduce code wrapping.

Anirudh cleans up code by removing a function prototype that was never
implemented and removed an unused field in the ice_sched_vsi_info
structure.

Kiran fixes a potential divide by zero issue by adding a check.

Victor cleans up the transmit scheduler by adjusting the stack variable
usage and added/modified debug prints to make them more useful.

Yashaswini updates the driver in VEB mode to ensure that the LAN_EN bit
is set if all the right conditions are met.

Christopher ensures the loopback enable bit is not set for prune switch
rules, since all transmit traffic would be looped back to the internal
switch and dropped.
