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

Message

Hawkins Jiawei June 29, 2023, 3:25 p.m. UTC

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.
