Subject: [net-next 02/14] net/mlx5: Remove unnecessary checks for slow path flag
Date: Mon, 25 Oct 2021 13:54:19 -0700 [thread overview]
Message-ID: <20211025205431.365080-3-saeed@kernel.org> (raw)
In-Reply-To: <20211025205431.365080-1-saeed@kernel.org>
From: Paul Blakey <paulb@nvidia.com>
After previous changes, caller (mlx5e_tc_offload_fdb_rules()) already
checks for the slow path flag, and if set won't call offload/unoffload
sample.
