Hi,
The VHOST_NET_SET_BACKEND could tell the user when the backend is created or destroyed.is usefull for the user but this command is lost in the protocol

sorry it is not need to add VHOST_NET_SET_BACKEND.I found i can reset in VHOST_GET_VRING_BASE because before the backend cleanup it will send VHOST_GET_VRING_BASE.

I guess it's a workaround, but I think it's an ugly one.
Let's add this command properly.
What's the best way to do this?
A feature bit? Or just add a new command and assume
remote ignores what it can't handle?
Nikolay, docs/specs/vhost-user.txt seems silent on this
aspect. Can you send a patch documenting it please?
