4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stephen Hemminger <stephen@xxxxxxxxxxxxxxxxxx>
[ Upstream commit 97f3efb64323beb0690576e9d74e94998ad6e82a ]
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.
Fixes: 0c195567a8f6 ("netvsc: transparent VF management")
