Subject: [PATCH] net/mlx5: fix startup when flow cannot be applied
When flows cannot be re-applied due to configuration modifications, the
start function should rollback the configuration done.
Fixes: 2097d0d1e2cc ("net/mlx5: support basic flow items and actions")

From: Shahaf Shuler <shahafs@mellanox.com>
Date: Thu, 2 Mar 2017 11:05:44 +0200
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.
