This small series enables virtio-net device type in VDUSE.
With it, basic operation have been tested, both with
virtio-vdpa and vhost-vdpa using DPDK Vhost library series
adding VDUSE support using split rings layout (merged in
DPDK v23.07-rc1).

Control queue support (and so multiqueue) has also been
tested, but requires a Kernel series from Jason Wang
relaxing control queue polling [1] to function reliably.

Jason promised to post a new version of that patch.
Right Jason?

Yes.

For now let's make sure CVQ feature flag is off?

We can do that and relax on top of my patch.

I agree? Do you prefer a features negotiation, or failing init (like
done for VERSION_1) if the VDUSE application advertises CVQ?

Assuming we will relax it soon, I think we can choose the easier way.
I guess it's just failing.

Thanks

Thanks,
