Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/16/24. 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/66dffe8a6d5eec1dfee17bfad85f5f5f9cac2265

Thanks.

Luca Boccassi

Subject: [PATCH] common/cnxk: fix link config for SDP

[ upstream commit 48054ca3842b0fc468e3e7931143dcb154b45921 ]

Link configure registers are invalid and should not be accessed
for SDP ports. But while on Txq release which does SQ flush calls
back pressure disable API which configures these link registers.

Fixes: 58debb813a8d ("common/cnxk: enable TM to listen on Rx pause frames")
