Not sure whether the queues should be static or dynamic (imagine direct interguest networking, one queue pair for each other guest), and how xmit queues would be selected by the guest (anything anywhere, or dst mac?).

The primary purpose of multiple queues is to maximise CPU utilisation,
so the number of queues is simply dependent on the number of CPUs
allotted to the guest.
