OK, I think other comments have died down, so it's time for a review. This
was the latest patch I could find.
The obvious way to do this is to use multiple pairs of virtqueues. Is this
silly for some reason? Yes, we're restricted to 32k ports.
It means that if we see the MULTIQUEUE feature, we can look for the other
queues. Our current MSI-X friendly API makes that a little painful, but
if we resolve that our code should be sweetness, no?
