What constitutes an "Intel vdev PMD"?  I thought these were all part
of the DPDK project?  It seems odd to me for you to pick and choose

What is the overall purpose of this RFC?  What benefit accrues to
those vdev PMDs that implement this change?  What penalty is imposed
on those that do not change?
