Subject: [PATCH rdma-next v2 2/4] RDMA/mlx5: Reduce QP table exposure
Date: Mon,  5 Jun 2023 13:14:05 +0300	[thread overview]
Message-ID: <bec0dc1158e795813b135d1143147977f26bf668.1685953497.git.leon@kernel.org> (raw)
In-Reply-To: <cover.1685953497.git.leon@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

driver.h is common header to whole mlx5 code base, but struct
mlx5_qp_table is used in mlx5_ib driver only. So move that struct
to be under sole responsibility of mlx5_ib.
