Subject: [PATCH rdma-next 7/8] net/smc: Move to client_supported callback
Date: Mon, 5 Apr 2021 08:49:59 +0300 [thread overview]
Message-ID: <20210405055000.215792-8-leon@kernel.org> (raw)
In-Reply-To: <20210405055000.215792-1-leon@kernel.org>
From: Parav Pandit <parav@nvidia.com>
Use newly introduced client_supported() callback to avoid client
additional if the RDMA device is not of IB type.
