Subject: [PATCH rdma-next 4/4] IB/mlx5: Implement callbacks for getting VFs GUID attributes
Date: Thu, 14 Nov 2019 15:31:26 +0200 [thread overview]
Message-ID: <20191114133126.238128-6-leon@kernel.org> (raw)
In-Reply-To: <20191114133126.238128-1-leon@kernel.org>
From: Danit Goldberg <danitg@mellanox.com>
Implement the IB defined callback mlx5_ib_get_vf_guid used to query FW
for VFs attributes and return node and port GUIDs.
