Subject: [PATCH mlx5-next 09/16] net/mlx5: Expose IP-in-IP TX and RX capability bits
Date: Fri, 20 Nov 2020 15:03:32 -0800	[thread overview]
Message-ID: <20201120230339.651609-10-saeedm@nvidia.com> (raw)
In-Reply-To: <20201120230339.651609-1-saeedm@nvidia.com>

From: Aya Levin <ayal@nvidia.com>

Expose FW indication that it supports stateless offloads for IP over IP
tunneled packets per direction. In some HW like ConnectX-4 IP-in-IP
support is not symmetric, it supports steering on the inner header but
it doesn't TX-Checksum and TSO. Add IP-in-IP capability per direction to
cover this case as well.

Note: only if both indications are turned on, the global
tunnel_stateless_ip_over_ip is on too.
