Just to clarify, it seems like what you are suggesting is just adding the "master" as a separate set of netdev ops or netdevice and to have virtio spawn two network devices, one slave and one master, if the BACKUP bit is set. Do I have that right? I am good with the code still living in the virtio driver and consolidation with other similar implementations and further improvement could probably happen later as part of some refactor.
