patch 'net/txgbe: fix link status check' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/04/26. 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/25d265a7272389170476253ca50b98ecfeb64e70

Thanks.

Kevin

Subject: [PATCH] net/txgbe: fix link status check

[ upstream commit 480f058c56743cce1f2c6fbde505094d4dce5a73 ]

The original code incorrectly used 'if (link_up)' instead of
'if (*link_up)', causing the condition to always evaluate to true
because the pointer itself is non-NULL. This led to incorrect speed
assignment.

Fixes: fb6eb170dfa2 ("net/txgbe: add basic link configuration for Amber-Lite")
