This patch introduces a mdev based hardware vhost backend.
This backend is built on top of the same abstraction used
in virtio-mdev and provides a generic vhost interface for
userspace to accelerate the virtio devices in guest.
This backend is implemented as a mdev device driver on top
of the same mdev device ops used in virtio-mdev but using
a different mdev class id, and it will register the device
as a VFIO device for userspace to use. Userspace can setup
the IOMMU with the existing VFIO container/group APIs and
then get the device fd with the device name. After getting
the device fd, userspace can use vhost ioctls on top of it
to setup the backend.

So at this point, looks like the only thing missing is IFC, and then all
these patches can go in.
But as IFC is still being worked on anyway, it makes sense to
address the minor comments manwhile so we don't need
patches on top.
Right?
Yeah, of course.
Thanks,

Please send V6 and I will ack there.
Thanks
