Hi,

FYI, your patch has been queued to stable release 20.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/21/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/9a7af96513d007af9b22516ef0112622e695d27e

Thanks.

Luca Boccassi

Subject: [PATCH] net/txgbe: check process type in close operation

[ upstream commit 21ed282505ed8f60f03a93a27ac01f4152b8ab40 ]

The secondary processes are not allowed to release shared resources.
Only process-private resources should be freed in a secondary process.
Most of the time, there is no process-private resource,
so the close operation is just forbidden in a secondary process.

Fixes: e1698e383c2a ("net/txgbe: add device init and uninit")
