Message

This series enables shadowed CVQ to intercept multiqueue commands through
shadowed CVQ, update the virtio NIC device model so qemu send it in a
migration, and the restore of that MQ state in the destination.

It needs to be applied on top of [1].

v2:
* Add vhost_vdpa_net_load_cmd helper to avoid out buffers castings.
* Make cvq_cmd_in_buffer virtio_net_ctrl_ack type.
