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/9502cde78b96b713f43d68055964d0b5c0747033

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: avoid crash in DCB config

[ 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")
