Yes, I agree. I'd also like to do more work on the macvlan extensions
to see if it works out without involving a socket. Passing the socket
into the vhost_net device is a nice feature of the current implementation
that we'd have to give up for something else (e.g. making the vhost
a real network interface that you can hook up to a bridge) if it were
to use virtio.

Unless I can come up with a solution that is clearly superior, I'm
taking back my objections on that part for now.
