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/5c4260919b86848745f0676f8e4179d9556221e6 Thanks.
