What exactly did you change here from my original driver ?
Your already changed the spec havily (w/o consulting me first), so I guess this driver hasn't so much in common w/ my original design.
Note that I made my original design decisions for good reaons (see virtio-dev list). It already support async notifications (IOW: irqs), had an easy upgrade path for future additions, etc.
Note #2: it's already implemented and running in the field (different kernels, different hypervisors, ...) - it just lacked the going through virtio comitte's formal specification process, which blocked mainlining.
Is there anything fundamentally wrong w/ my original design, why you invented a completely new one ?
