Subject: [net-next 05/12] net/mlx5e: Maximize ip tunnel key usage on the TC offloading path
Date: Tue, 24 Jan 2017 22:16:45 +0200 [thread overview]
Message-ID: <20170124201652.2920-6-saeedm@mellanox.com> (raw)
In-Reply-To: <20170124201652.2920-1-saeedm@mellanox.com>
From: Or Gerlitz <ogerlitz@mellanox.com>
Use more fields out of the tunnel key (e.g the tunnel source IP address)
provided by upper layers for the route lookup done on the encap offload path.
