patch 'ethdev: fix port state when stop' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/d096c590deef6b8352eec0ca5c67fb9cb81b39a7

Thanks.

Subject: [PATCH] ethdev: fix port state when stop
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 74b74269978c2790bc49238029e00b7c6e81c450 ]

Currently, 'dev_started' is always set to be 0 when dev stop, whether
it succeeded or failed. This is unreasonable and this patch fixed it.

Fixes: 62024eb82756 ("ethdev: change stop operation callback to return int")
