Subject: [net 3/4] net/mlx5e: E-Switch, Specify flow_source for rule with no in_port
Date: Thu, 30 Jul 2020 18:57:51 -0700	[thread overview]
Message-ID: <20200731015752.28665-4-saeedm@mellanox.com> (raw)
In-Reply-To: <20200731015752.28665-1-saeedm@mellanox.com>

From: Jianbo Liu <jianbol@mellanox.com>

The flow_source must be specified, even for rule without matching
source vport, because some actions are only allowed in uplink.
Otherwise, rule can't be offloaded and firmware syndrome happens.

Fixes: 6fb0701a9cfa ("net/mlx5: E-Switch, Add support for offloading rules with no in_port")
