This implements virtio_net for the mergeable buffers and big_packet
modes. I tested this with vhost_net running on qemu and did not see
any issues. For testing num_buf > 1 I added a hack to vhost driver
to only but 100 bytes per buffer.

So where are we with this?

There is one possible issue with a hang that Michael pointed out. I can
either spin a v6 or if you pull this v5 series in I can post a bugfix
for it. I am not seeing the issue in practice XDP virtio has been up
and running on my box here for days without issue.

If that's the case then please spin a v6 and I'll apply it.
