Add two NLA's that allow configuration of Infiniband node or port GUIDs
by referencing the IPoIB net device set over then physical function. The
format to be used is as follows:
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

Strange name for a variable, if sscanf() returns # of fields read... In
fact, you don't even need this variable.
