[dpdk-stable] please help backporting some patches to stable release 18.08.1

[Kevin Traynor]

Hi commit authors (and maintainers),

I didn't manage to apply following commits from upstream to stable branch
18.08: conflict happens. I'm wondering can the authors check the following
list and backport those patches belong to you?

FYI, branch 18.08 is located at tree:
   git://dpdk.org/dpdk-stable

It'd be great if you could do that in one week. Also, please add a
heading line like below before the commit log body:
    [ backported from upstream commit xxx ]

Example: http://dpdk.org/browse/dpdk-stable/commit/?h=16.07&id=c4831394c7d1944d8ec27d52c22997f20d19718e

Also please mention the target stable in the subject line, as we have more than one
at the same time, for example:

    [PATCH 18.08] foo/bar: fix baz

With git send-email, this can be achieved by appending the parameter:

    --subject-prefix='18.08'

Please let me know if you have any comments, say, need more time, or it's
worthless to packport it. And please send it to "stable at dpdk.org", but not
"dev at dpdk.org".

Thanks.

Kevin Traynor
