Re: [PATCH v3 0/6] Vhost-vdpa Shadow Virtqueue Offloads support

[Lei Yang]

Hello Hawkins

QE based on the qemu command line [1] to test this series with the
following scenarios: reboot,shutdown,hotplug/unplug,ping, and
offloads(tx,sg,tso,gso,gro), everything is working fine. It's just
that even without applying your patch to test offload there is no
error like "vdpa svq is not available for feature 4".

[1] -device '{"driver": "virtio-net-pci", "mac": "00:11:22:33:44:00",
"id": "net0", "netdev": "hostnet0", "ctrl_guest_offloads": true,
"bus": "pcie-root-port-3", "addr": "0x0"}'  \
-netdev vhost-vdpa,id=hostnet0,vhostdev=/dev/vhost-vdpa-0,x-svq=on \
