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/71b400b1db4be3f067268d9df30d4ebe8c7b3851 Thanks. Kevin --- >From 71b400b1db4be3f067268d9df30d4ebe8c7b3851 Mon Sep 17 00:00:00 2001 From: Hemant Agrawal Date: Mon, 6 Oct 2025 13:34:02 +0530 Subject: [PATCH] net/enetfec: fix buffer descriptor size configuration [ upstream commit f034c096b86ed79345cc1f83c6191713b2814fb0 ] The driver previously allowed arbitrary descriptor counts, which could lead to misaligned buffer allocations. This patch enforces the use of fixed descriptor ring sizes for both RX and TX queues, ensuring proper buffer allocation and avoiding potential runtime issues.
