There is some issues in this commit, first the title line exceed the
75 characters.

Second it is submitted on the dev mailing list whereas it seems to be
targeting a stable branch, in should have been posted on
stable@dpdk.org and according to the sha-1 I would say the target is
the 17.08.

Can you make things clearer?
