Subject: [net-next 13/14] net/mlx5: DR, Add support for flow table id destination action
Date: Fri, 13 Mar 2020 18:16:21 -0700	[thread overview]
Message-ID: <20200314011622.64939-14-saeedm@mellanox.com> (raw)
In-Reply-To: <20200314011622.64939-1-saeedm@mellanox.com>

From: Alex Vesker <valex@mellanox.com>

This action allows to go to a flow table based on the table id.
Goto flow table id is required for supporting user space SW.
