Subject: [net-next 13/15] net/mlx5e: rep: Improve reg_cX conditions
Date: Thu, 11 Mar 2021 14:37:21 -0800 [thread overview]
Message-ID: <20210311223723.361301-14-saeed@kernel.org> (raw)
In-Reply-To: <20210311223723.361301-1-saeed@kernel.org>
From: Saeed Mahameed <saeedm@nvidia.com>
There is no point of calculating reg_c1 or overriding reg_c0 if we are
going to abort the function.
