Some more netvsc performance related changes.
The biggest benefit comes from lowering the hypervisor polling rate
from 100us to 50us.  Supporting tx_done_cleanup can also help some
applications get through the send completions faster.

Stephen Hemminger (4):
  netvsc: chimney buffer size error handling
  bus/vmbus: add host latency tuning function
  netvsc: set lower host latency
  netvsc: implement tx_done_cleanup
