Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. 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/a4a27aa3e0f8a870de14f33463180c3b9af4c8de

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: fix lcore ID restriction

[ upstream commit 2bf44dd14fa50fa95e090058ec83c2eb96b64ac5 ]

With modern CPUs, it is possible to have higher
CPU count thus we can have higher RTE_MAX_LCORES.
In testpmd application, the current config forwarding
cores option "--nb-cores" is hard limited to 255.

The patch fixes this constraint and also adjusts the lcore
data structure to 32-bit to align with rte lcore APIs.

Fixes: af75078fece3 ("first public release")
