| Subject: hv_netvsc: set master device |
| |
| From: Stephen Hemminger <stephen@networkplumber.org> |
| |
| [ 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") |
