From cc8e27cc97318471b7e707932d5b93b0d5f70830 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Fri, 11 Mar 2016 22:58:34 +0200 Subject: net/core: Add support for configuring VF GUIDs Add two new NLAs to support configuration of Infiniband node or port GUIDs. New applications can choose to use this interface to configure GUIDs with iproute2 with commands such as: ip link set dev ib0 vf 0 node_guid 00:02:c9:03:00:21:6e:70 ip link set dev ib0 vf 0 port_guid 00:02:c9:03:00:21:6e:78 A new ndo, ndo_sef_vf_guid is introduced to notify the net device of the request to change the GUID.
