Subject: [net-next 09/15] net/mlx5e: Delete obsolete IPsec code
Date: Thu, 19 Oct 2023 20:04:16 -0700	[thread overview]
Message-ID: <20231020030422.67049-10-saeed@kernel.org> (raw)
In-Reply-To: <20231020030422.67049-1-saeed@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

After addition of HW managed counters and implementation drop
in flow steering logic, the code in driver which checks syndrome
is not reachable anymore.

Let's delete it.
