Subject: [PATCH rdma-next 6/8] IB/opa_vnic: Move to client_supported callback
Date: Mon,  5 Apr 2021 08:49:58 +0300
Message-ID: <20210405055000.215792-7-leon@kernel.org> (raw)
In-Reply-To: <20210405055000.215792-1-leon@kernel.org>

From: Parav Pandit <parav@nvidia.com>

Move to newly introduced client_supported callback
Avoid client registration using newly introduced helper callback if the
IB device doesn't have OPA VNIC capability.
