I think we should hold off on this sort of patch at first. I know it
improves performance, but it's very hack-ish. I have a similar patch[1]
that improves performance more but is even more hack-ish.
I think we have to approach this by not special cases virtio-net to know
about the tap fd, but to figure out the interface that virtio-net would
need to be efficient, and then refactor the net interface to look like
that. Then we can still support user, pcap, and the other network
transports.

While you are right in principle, high performance networking is long
overdue in kvm so I applied that patch. Once a mega async dma framework
is added to qemu, we'll just revert that patch prior to adding the glue
to said framework.
