Subject: [net-next 13/15] net/mlx5: Store vport in struct mlx5_devlink_port and use it in port ops
Date: Tue, 22 Aug 2023 22:10:10 -0700 [thread overview]
Message-ID: <20230823051012.162483-14-saeed@kernel.org> (raw)
In-Reply-To: <20230823051012.162483-1-saeed@kernel.org>
From: Jiri Pirko <jiri@nvidia.com>
Instead of using internal devlink_port->index to perform vport lookup in
every devlink port op, store the vport pointer to the container struct
mlx5_devlink_port and use it directly in port ops.
