vDPA device is a device that uses a datapath which complies with the

This RFC introduce the vDPA support in qemu
Looks good overall, see comments inline.
And I think we need reorder the patches and split some patches into
smaller ones.
E.g
1) qemu_get_peer
2) queue_enabled method for virtio-bus
3) queue_enabled for virtio-pci
4) set_vring_ready for vhost_ops
5) vhost_set_state for vhost_ops
6) call vhost_set_state in virtio_net_vhost_status()
7) generic vdpa support
8) vhost-vdpa net backend
Thanks

net: Introduce qemu_get_peer
vhost-vdpa: introduce vhost-vdpa net client
vhost-vdpa: implement vhost-vdpa backend
