Also I see that /sys/class/infiniband/mlx4_0/node_guid contains 0002:c903:000b:5348, that's ib0's end-of-address minus one, and ib1's end-of-address minus two. But I have no idea what GID, LID and GUID really are so I don't know if there's anything to do with this. We should ask some IB kernel/hardware guys in case there is some guarantee about mac address and/or GID/LID ordering. Brice
