patch 'net/ixgbe/base: fix compilation warnings' has been queued to stable release 24.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/23/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/0b5f911820a566be77347ea837db9086a56e7adb

Thanks.

Kevin

Subject: [PATCH] net/ixgbe/base: fix compilation warnings

[ upstream commit ca361b5ab1ba8ec9191b8376a8be0e3935823596 ]

We can remove almost all of the "unused parameter" and "unused variable"
warnings by just improving the macro definitions in the osdep.h header.
Remaining two instances can be fixed by just one-line additions to the
code, so add those to give us a clean build with the warnings enabled.

Fixes: af75078fece3 ("first public release")
Fixes: c6cb313da739 ("net/ixgbe/base: add link management for E610")
