patch 'net/axgbe: fix 100M SGMII mode' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/d790fd1e38372741abe6fbc6167340de74ac4a71

Thanks.

Kevin

Subject: [PATCH] net/axgbe: fix 100M SGMII mode

[ upstream commit 11b918959cd924fc6ad09d8cae1a86411490218a ]

In SGMII 100M mode, set MAC speed to 100M instead of 1G,
and add the PHY implementation for SGMII 100 mode.

Fixes: a5c7273771e8 ("net/axgbe: add phy programming APIs")
