Merge branch 'hv_netvsc-minor-fixes'

Stephen Hemminger says:

====================
hv_netvsc: minor fixes

These are improvements to netvsc driver. They aren't functionality
changes so not targeting net-next; and they are not show stopper
bugs that need to go to stable either.

v2
   - drop the irq flags patch, defer it to net-next
   - split the multicast filter flag patch out
   - change propogate rx mode patch to handle startup of vf
====================
