From 64050cdad0983ad8060e33c3f4b5aee2366bcebd Mon Sep 17 00:00:00 2001 From: Aya Levin Date: Sun, 24 Oct 2021 11:47:41 +0300 Subject: [PATCH] Revert "net/mlx5e: Block offload of outer header csum for UDP tunnels" This reverts commit 6d6727dddc7f93fcc155cb8d0c49c29ae0e71122. Although the NIC doesn't support offload of outer header CSUM, using gso_partial_features allows offloading the tunnel's segmentation. The driver relies on the stack CSUM calculation of the outer header. For this, NETIF_F_GSO_UDP_TUNNEL_CSUM must be a member of the device's features.
