Note that this commit is not from upstream, instead, it's from
dpdk-next-net.
Another thing worth noting is the commit hash will likely change
after it get applied to upstream, for, AFIAK, they do rebase for
merging dpdk-next tress. That's the reason we don't directly pick
commits from dpdk-next trees.
For this one, I will apply it without above commit info. I have
also applied the others.
Thanks.
