Subject: [PATCH rdma-next 08/18] RDMA/mlx5: Split scatter CQE configuration for DCT QP
Date: Mon, 20 Apr 2020 18:10:55 +0300	[thread overview]
Message-ID: <20200420151105.282848-9-leon@kernel.org> (raw)
In-Reply-To: <20200420151105.282848-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

DCT QPs have separate creation flow and can be easily extracted
from configure_responder_scat_cqe(), this makes both updated
functions more clear.
