[RFC PATCH v2 0/3] virtio-net: graceful drop of vhost for TAP

[Yuri Benditovich]

Allow fallback to userspace only upon migration, only for specific features
and only if 'vhostforce' is not requested.

Changes from v1:
Patch 1 dropeed (will be submitted in another series)
Added device callback in case the migration should fail due to missing features

Yuri Benditovich (3):
  net: add ability to hide (disable) vhost_net
  virtio: introduce 'missing_features_migrated' device callback
  virtio-net: implement missing_features_migrated callback
