[PATCH v2] vhost: introduce mdev based hardware backend
....
We already have VHOST_SET_OWNER in vhost now, parent can handle
the commands in its .kick_vq() which is called by vq's .handle_kick
callback. Virtio-user did something similar:

This probably means a process context is required, something like
kthread that is used by vhost which seems a burden for parent. Or we can
extend ioctl to processing kick in the system call context.
