This series enables shadowed CVQ to intercept rx commands related to VIRTIO_NET_F_CTRL_RX_EXTRA feature through shadowed CVQ, update the virtio NIC device model so qemu send it in a migration, and the restore of that rx state in the destination.
To test this patch series, I modify the `n->parent_obj.guest_features` value in vhost_vdpa_net_load_rx() using gdb, as the Linux virtio-net driver does not currently support the VIRTIO_NET_F_CTRL_RX_EXTRA feature. Note that this patch should be based on [1], which has not been merged yet. I will submit the v2 patch after they are merged.
