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 07/17/24. 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/8b161ee9179e028aa632d53d9015add2eae79c87

Thanks.

Luca Boccassi

Subject: [PATCH] net/ngbe: add special config for YT8531SH-CA PHY

[ upstream commit 79be49dd2d655f2f5e830f33115528276a994bae ]

YT8531SH-CA PHY will switch to SDS space automatically when UTP and
SDS media are not present, causing failure to link up. Add the special
configuration to fix it.

Fixes: 3d0af7066759 ("net/ngbe: setup PHY link")
Fixes: 1c44384fce76 ("net/ngbe: support custom PHY interfaces")
