Just noticed now that this driver landed upstream.  Can I ask that you
guys please register IDs with the virtio TC and not just pick a number
at random? In particular this is way outside allowed range.

IDs should also be listed in include/uapi/linux/virtio_ids.h

If people just pick random numbers like this collistions are unavoidable.

List of IDs is part of virtio spec, chapter "Device Types".

Please do this change now before this goes out to production!

Thanks!
