Message-ID: <20171227075759.15289-6-leon@kernel.org> (raw)
In-Reply-To: <20171227075759.15289-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
Link layer operates on port layer, hence it should check
it existence before execution commands.
Fixes: da990ab40a92 ("rdma: Add link object")
