Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/19/25. 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/ec6a60f0806121520ffd06c87eb3e00f488d76dc

Thanks.

Luca Boccassi

Subject: [PATCH] net/igc/base: fix typo in LTR calculation

[ upstream commit ce11274c5c7188322cc141cdce8cd0680e76f79f ]

The LTR maximum value was incorrectly written using the scale from the
LTR minimum value. This would cause incorrect values to be sent, in
cases where the initial calculation leads to different min/max scales.
Fix the typo to correctly calculate the LTR maximum value.

Fixes: 8cb7c57d9b3c ("net/igc: support device initialization")
