patch 'ethdev: fix port state when stop' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/b6db13dcd97679cfa54eecff1328dabcdff4b475

Thanks.

Kevin

Subject: [PATCH] ethdev: fix port state when stop

[ 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")
