[PATCH RFC 0/2] Vhost-vdpa Shadow Virtqueue _F_CTRL_RX_EXTRA commands support

[Hawkins Jiawei <yin31149@gmail.com>]

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.
