[PATCH net] hv_netvsc: set master device

[PATCH net] hv_netvsc: set master device

[Stephen Hemminger]

The hyper-v transparent bonding should have used master_dev_link.
The netvsc device should look like a master bond device not
like the upper side of a tunnel.

This makes the semantics the same so that userspace applications
looking at network devices see the correct master relationshipship.

Applied and queued up for -stable.
