Subject: [PATCH rdma-next 02/18] RDMA/mlx5: Delete impossible GSI port check
Date: Mon, 20 Apr 2020 18:10:49 +0300	[thread overview]
Message-ID: <20200420151105.282848-3-leon@kernel.org> (raw)
In-Reply-To: <20200420151105.282848-1-leon@kernel.org>

From: Leon Romanovsky <leonro@mellanox.com>

GSI QP is created in the kernel with very strict parameters,
there is no possible way that port number will be wrong in
such flow.
