We normally expect vdpa to use the modern interface.
However for consistency, let's use same APIs as vhost
for legacy guests.

virtio: introduce a vDPA based transport2020-04-01T16:06:26ZJason Wangjasowang@redhat.com2020-03-26T14:01:22Zurn:sha1:c043b4a8cf3b16fbdcaec1126841431c33b16e98
This patch introduces a vDPA transport for virtio. This is used to
use kernel virtio driver to drive the vDPA device that is capable
of populating virtqueue directly.
A new virtio-vdpa driver will be registered to the vDPA bus, when a
new virtio-vdpa device is probed, it will register the device with
vdpa based config ops. This means it is a software transport between
vDPA driver and vDPA device. The transport was implemented through
bus_ops of vDPA parent.
