Subject: [PATCH mlx5-next 07/14] net/mlx5: detect and enable bypass port select flow table
Date: Wed, 7 Sep 2022 16:36:29 -0700 [thread overview]
Message-ID: <20220907233636.388475-8-saeed@kernel.org> (raw)
In-Reply-To: <20220907233636.388475-1-saeed@kernel.org>
From: "Liu, Changcheng" <jerrliu@nvidia•com>
Use port selection capability port_select_flow_table_bypass
bit to detect and enable explicit port affinity even when
in lag hash mode.
