I have similar patches, but you really need to fix the driver
so that control queue is brought up on dev_init, not start.
It makes sense to allow code to change modes independent of whether
driver has been started or not.
Also, the virtio driver is doing reset on stop. This may not be
best solution because it conflicts with what Linux driver is doing.
Another current bug is that virtio DPDK driver is broken on latest
KVM. It works with Debian stable, but not with Debian testing.
Too busy to investigate further.
Hi Stephen,

Yes, agree with you on these 2 existing issues, but I'd like to use a separate patch to fix them,
And let this patch focus on multicast feature.
If you have already a patch to fix them, that's great.

Is this bug introduced by this patch or it is an existing bug?
If it is introduced by this patch, a v2 patch is necessary,
Otherwise, a separate patch is suggested.

It is an existing bug (in KVM). Not getting warm response from upstream.
