Since RC2 is fast approaching, I've taken the first 3 patches of this
series into next-net-intel.

For the remaining 3 patches, the two driver patches need some more
discussion and probably rework. The final patch, for test-pmd, goes in a
different tree (not next-net-intel), so please send it as a separate
standalone patch.

Thanks,
