v2:
- Change the git comments based on Matan's feedback
https://dpdk.org/dev/patchwork/patch/35104/
- Some platform like thunderx + l3fwd showed 1% regression in
the performance with 5b7ba31148a8 ("ethdev: add port ownership")
in one port setup.
- If there are no objection for this change then request to
take it for v18.02 release.
