[PATCH RFC v2 0/4] Vhost-vdpa Shadow Virtqueue _F_CTRL_RX commands support

[Hawkins Jiawei <yin31149@gmail.com>]

This series enables shadowed CVQ to intercept rx commands related to
VIRTIO_NET_F_CTRL_RX 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.

Note that this patch should be based on [1], which have not
been merged. I will submit a new version of patch after it is merged.
