Subject: [PATCH mlx5-next 08/18] net/mlx5: Move legacy drop counter and rule under legacy structure
Date: Mon, 28 Oct 2019 23:35:11 +0000	[thread overview]
Message-ID: <20191028233440.5564-9-saeedm@mellanox.com> (raw)
In-Reply-To: <20191028233440.5564-1-saeedm@mellanox.com>

From: Parav Pandit <parav@mellanox.com>

To improve code readability, move legacy drop counters and droup rule
under legacy structure.

While at it,
(a) prefix drop flow counters helper with legacy_.
(b) nullify the rule pointers only if they were valid.
