[dpdk-stable] please help backporting some patches to LTS release 16.11.9

[Luca Boccassi]

Hi commit authors (and maintainers),

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

FYI, branch 16.11 is located at tree:
   git://dpdk.org/dpdk-stable

It'd be great if you could do that in one or two weeks. 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 LTS in the subject line, as we have more than one
at the same time, for example:

    [PATCH 16.11] foo/bar: fix baz

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

    --subject-prefix='16.11'

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.

Luca Boccassi
