Subject: [PATCH mlx5-next 12/15] net/mlx5: E-Switch, Enable vport metadata matching if firmware supports it
Date: Mon, 17 Jun 2019 19:23:32 +0000	[thread overview]
Message-ID: <20190617192247.25107-13-saeedm@mellanox.com> (raw)
In-Reply-To: <20190617192247.25107-1-saeedm@mellanox.com>

From: Jianbo Liu <jianbol@mellanox.com>

As the ingress ACL rules save vhca id and vport number to packet's
metadata REG_C_0, and the metadata matching for the rules in both fast
path and slow path are all added, enable this feature if supported.
