Subject: [PATCH net-next 05/12] net/mlx5e: Move mlx5e_rq struct declaration
Date: Sat, 25 Mar 2017 00:52:07 +0300	[thread overview]
Message-ID: <20170324215214.25711-6-saeedm@mellanox.com> (raw)
In-Reply-To: <20170324215214.25711-1-saeedm@mellanox.com>

Move struct mlx5e_rq and friends to appear after mlx5e_sq declaration in
en.h.

We will need this for next patch to move the mlx5e_sq instance into
mlx5e_rq struct for XDP SQs.
