-Subject: [PATCH] net/mlx5: add hardware checksum offload for tunnel packets
-
-Prior to this commit Tx checksum offload was supported only for the
-inner headers.
-This commit adds support for the hardware to compute the checksum for the
-outer headers as well.
-
-The support is for tunneling protocols GRE and VXLAN.
