patch 'ethdev: fix port close in secondary process' 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/fa4da49c81448a520107c072dee1614dd048234e

Thanks.

Subject: [PATCH] ethdev: fix port close in secondary process
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit ea6101a8e483f3b6ec505c91b7e72ab1628dab1f ]

Secondary process needs to close device to release process private
resources.  But secondary process should not be obliged to wait for
device stop before closing ethdev.

Fixes: febc855b358e ("ethdev: forbid closing started device")
