From 54e1217b90486c94b26f24dcee1ee5ef5372f832 Mon Sep 17 00:00:00 2001 From: Aya Levin Date: Wed, 26 May 2021 10:40:36 +0300 Subject: [PATCH] net/mlx5e: Block offload of outer header csum for GRE tunnel The device is able to offload either the outer header csum or inner header csum. The driver utilizes the inner csum offload. So, prohibit setting of tx-gre-csum-segmentation and let it be: off[fixed].
