Not sure if I've mentioned it, but it is a quad I350. Port 0 and 3 on
host only, and 1 and 2 are being used by DPDK in a guest. The
challenge was to make a ping go from port 0 to 3 and back, via a
somewhat modified DPDK l2fwd example. Port 1 and 2 had two virtual
functions each, and each such pair was given to an instance of this
l2fwd example.

If you need more help with how we set things up, I'll be happy to help you.
