Subject: [net 05/11] Revert "net/mlx5e: Block offload of outer header csum for UDP tunnels"
Date: Thu, 6 Jan 2022 16:58:25 -0800 [thread overview]
Message-ID: <20220107005831.78909-6-saeed@kernel.org> (raw)
In-Reply-To: <20220107005831.78909-1-saeed@kernel.org>
From: Aya Levin <ayal@nvidia.com>
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.
Fixes: 6d6727dddc7f ("net/mlx5e: Block offload of outer header csum for UDP tunnels")
