It will be pushed if I get no objections before 03/13/24. 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/92f6f10e9daf7a07899e7567c6430602c0ba3cd9 Thanks. Kevin --- >From 92f6f10e9daf7a07899e7567c6430602c0ba3cd9 Mon Sep 17 00:00:00 2001 From: Sunil Kumar Kori Date: Mon, 26 Feb 2024 19:05:30 +0530 Subject: [PATCH] net/cnxk: fix MTU limit [ upstream commit 402de2fd8729b61a3ace67c597e99893acb426d4 ] Device can support maximum frame size up to 9212 bytes. While configuring MTU, overhead is considered as ethernet header size, CRC and 2 * (VLAN tags) which translates to 26 bytes. Exposed overhead to the user via rte_eth_dev_info() is 18 bytes which were leading to set wrong Rx frame size.
