Michael Chan says:

====================
bnxt_en: Updates for net-next.

This series includes updating the firmware interface, adding
methods to get and set VEPA/VEB bridge modes, some minor DCBX and ETS
refinements, and 3 patches from Sathya Perla to implement initial
VF representors for SRIOV switching.
====================
