From f3ed653cd4191ce42b27b2fb524418832f7d6c2d Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Mon, 2 May 2016 09:38:49 -0700 Subject: [PATCH] net/mlx5e: Fix IPv6 tunnel checksum offload The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that and drops 2 features that don't actually need to be supported in hw_enc_features since they are Rx features and don't actually impact anything by being present in hw_enc_features.
