Merge branch 'netvsc-enhancements' 

Stephen Hemminger says:

====================
netvsc driver enhancements for net-next

Lots of little things in here. Support for minor more ethtool control,
negotiation of offload parameters with host (based on FreeBSD) and
several cleanups.
====================
