To make progress on this I think the spec needs to be close to something that can be included into the official virtio-specification. Have you proposed the specification for inclusion there? This is because I can't merge a driver that might be incompatible to future implementations because the specification needs to be changed on its way to an official standard. I had a short discussion with Michael S. Tsirkin about that and from what I understood the spec needs to be proposed for inclusion on the virtio-comment[1] mailing list and later the TC needs to vote on it. Please work with Michael on this to get the specification official (or at least pretty close to something that will be part of the official virtio standard).
