Subject: [PATCH mlx5-next 06/11] net/mlx5: E-switch, Combine metadata enable/disable functionality
Date: Mon, 29 Jul 2019 21:13:02 +0000 [thread overview]
Message-ID: <20190729211209.14772-7-saeedm@mellanox.com> (raw)
In-Reply-To: <20190729211209.14772-1-saeedm@mellanox.com>
From: Parav Pandit <parav@mellanox.com>
Except bit toggling code, rest of the code is same to enable/disable
metadata passing functionality.
Hence, combine them to single function and control using enable flag.
Also instead of checking metadata supported at multiple places,
fold into the helper function.
