patch 'app/testpmd: fix out-of-bound reference in offload config' has been queued to stable release 22.11.8

[luca.boccassi@gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/09/25. 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/6737b184aac935441fad1750704cd8e4eb7eed29

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: fix out-of-bound reference in offload config

[ upstream commit 8f847023dd16cb6e5858756d7ec16c940ac6eee9 ]

When configuring offloads, need to check the port id before
indexing into the ports[] array. This can easily be done
by moving the call to oh_dev_conf_get_print_err() to before
the checks for port stopped.

Fixes: c73a9071877a ("app/testpmd: add commands to test new offload API")
