[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/15/24. 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://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=9cb9b9c8a0508b9e9b3074611636760c6cd24cae

[ 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")
