It will be pushed if I get no objections before 11/05/25. 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/2b6a79110e9fc358af06466b73cee71a8e9caf2e Thanks. Kevin --- >From 2b6a79110e9fc358af06466b73cee71a8e9caf2e Mon Sep 17 00:00:00 2001 From: Shani Peretz Date: Thu, 18 Sep 2025 08:43:25 +0300 Subject: [PATCH] net/mlx5: fix MTU initialization [ upstream commit ee6aa2cb66512cd57b69ffe07efbd7f09789c9b2 ] Currently with mlx5 PMD, rte_eth_dev_get_mtu() doesn't return the MTU the device was set with, but the default one. It happens because mlx5_dev_spawn() is not setting the eth_dev->data->mtu field after getting the actual MTU from the driver, so the default value is kept. This patch fixes the issue by retrieving setting the value of priv->mtu to eth_dev->data->mtu.
