Hi Konrad.

I tested this version of the patch:
https://lkml.org/lkml/2019/10/13/42

It was tested for throughput with DPDK's testpmd (as described in
http://doc.dpdk.org/guides/howto/virtio_user_as_exceptional_path.html)
and kernel pktgen. No latency tests were performed by me. Maybe it is
interesting to perform a latency test or just a different set of tests
over a recent version.

Thanks!
