Subject: [net-next V2 03/15] net/mlx5e: Honor user choice of IPsec replay window size
Date: Fri, 20 Oct 2023 23:46:08 -0700 [thread overview]
Message-ID: <20231021064620.87397-4-saeed@kernel.org> (raw)
In-Reply-To: <20231021064620.87397-1-saeed@kernel.org>
From: Leon Romanovsky <leonro@nvidia.com>
Users can configure IPsec replay window size, but mlx5 driver didn't
honor their choice and set always 32bits. Fix assignment logic to
configure right size from the beginning.
Fixes: 7db21ef4566e ("net/mlx5e: Set IPsec replay sequence numbers")
