I'm not sure how stable above ops are.
It's the kernel internal API, so there's no strict requirement for this.
We will export a version value for userspace for compatibility.
Does it make sense if defining

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.

Hi all:
There are hardwares that can do virtio datapath offloading while
having its own control path. This path tries to implement a mdev based
unified API to support using kernel virtio driver to drive those
devices. This is done by introducing a new
mdev_vfio module
- require to specify the type of bus when registering mdev device and
