This seems to share nothing with mdev (ie mdev-vfio), why
This patch implements a mediated virtio bus over mdev framework. This
will be used by the future virtio-mdev and vhost-mdev on top to allow
driver from either userspace or kernel to control the device which is
capable of offloading virtio datapath.
