From bea4e1f6c6c5744d467ebf8b0699f5e391835130 Mon Sep 17 00:00:00 2001 From: Mark Bloch Date: Tue, 28 Aug 2018 14:18:47 +0300 Subject: [PATCH] net/mlx5: Expose new packet reformat capabilities Expose new abilities when creating a packet reformat context. The new types which can be created are: MLX5_REFORMAT_TYPE_L2_TO_L2_TUNNEL: Ability to create generic encap operation to be done by the HW. MLX5_REFORMAT_TYPE_L3_TUNNEL_TO_L2: Ability to create generic decap operation where the inner packet doesn't contain L2. MLX5_REFORMAT_TYPE_L2_TO_L3_TUNNEL: Ability to create generic encap operation to be done by the HW. The L2 of the original packet is dropped.
