The netvsc PMD is faster than the kernel but is still slow
on receiving packets. These patches help.

Stephen Hemminger (4):
  netvsc: change rx descriptor setup and sizing
  netvsc: avoid over filling receive descriptor ring
  netvsc: implement queue info get handles
  netvsc/vmbus: avoid signalling host on read
