Subject: [PATCH rdma-next 20/27] RDMA/mlx5: Enable reformat on NIC RX if supported

From: Leon Romanovsky <[email-masked]>
Date: Sun, 29 Jul 2018 15:58:58 +0300

From: Mark Bloch <[email-masked]>

A L3_TUNNEL_TO_L2 decap flow action requires to enable the encap bit on
the Flow table, enable it if supported. This will allow to attach those
flow actions to NIC RX steering. We don't enable if running on a
representor.
