patch 'app/testpmd: relax number of TCs in DCB command' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/28/25. 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=b448d39192cfb93928c9b654d8ee4be97cab7206

Thanks.

Subject: [PATCH] app/testpmd: relax number of TCs in DCB command
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5f2695ee948ddaf36050f2d6b58a3437248c1663 ]

Currently, the "port config 0 dcb ..." command only supports 4 or 8
TCs. Other number of TCs may be used in actual applications.

This commit removes this restriction.

Fixes: 900550de04a7 ("app/testpmd: add dcb support")
