It makes me smile :)
You basically explain that it's more complicated to properly merge two
different implementations than just throwing a new one in the big DPDK bucket.
My opinion is that it should not be integrated as is because we must try to
make DPDK something else than a trash bucket.

Thanks for continuing your effort to make DPDK easier and better.
