patch 'app/testpmd: avoid crash in DCB config' has been queued to stable release 23.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/10/25. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=afcc3d93754bba06e1797f4e3ab2f4b88c5d9cf4

Thanks.

[ upstream commit d646e219b34ffc4d531f3703fc317e7cff9a25ae ]

The "port config dcb ..." command will segment fault when input with
invalid port id, this patch fixes it.

Fixes: 9b53e542e9e1 ("app/testpmd: add priority flow control")
