My scripts first run "git format-patch", do some edits (like adding the
original commit info), then run "git am" to apply it. It failed.

I then tried "git cherry-pick" just now, as you stated, yes, it works.
Rerun "git am -3" shows that the conflict could be auto resolved.

So anyway, thanks for the backport! It's been queued to my local 16.11
branch, and it will be pushed to dpdk.org this Sat. if I got no
objections.
