Subject: [net-next 09/17] net/mlx5e: RX, Generalise name of non-linear SKB head size
Date: Fri, 1 Jun 2018 17:05:36 -0700 [thread overview]
Message-ID: <20180602000544.18717-10-saeedm@mellanox.com> (raw)
In-Reply-To: <20180602000544.18717-1-saeedm@mellanox.com>
From: Tariq Toukan <tariqt@mellanox.com>
Make name more generic by dropping MPWRQ from it, as it will be
used also in Legacy RQ in a downstream patch.
