My macvtap zero copy is incomplete, I am testing sendmsg only now. The
initial performance is not good especially for latency (zero copy vs.
copy). I am still working on it to find out why and how to improve.
That's the reason I am eager to know your performance results and how
much performance gain you have seen.

Since your patch has completed. I would try your patch here for
performance. If you have some performance results to share here that
would be great.
