vDPA drivers are vendor-specific and expected to talk to vendor
NIC. I.e. there are significant chances to share code with
network drivers (e.g. base driver). Should base driver be moved
to drivers/common in this case or is it still allows to have
vdpa driver in drivers/net together with ethdev driver?
