[dpdk-stable] patch 'net/null: remove redundant check' has been queued to LTS release 18.11.9

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/03/20. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/4fcd7720f7e126eb36ee1367956e184f5f44cac2

Thanks.

Kevin.

Subject: [PATCH] net/null: remove redundant check

[ upstream commit c21a276bd8f3d4c5210ccd2074f7a87a7d00b3e4 ]

There is no need to check if the argument exist or not,
`rte_kvargs_process` returns success if the argument is not provided at
all.

Fixes: c743e50c475f ("null: new poll mode driver")
