You should have a "Address" info attribute in each eth object containing
something like 80:34:00:48:fe:80:00:00:00:00:00:01:00:02:c9:03:00:0b:53:49
Is this useful?
Otherwise, I don't see any way to link IB ports with net interfaces in
* My /sys/class/infiniband/mlx4_0 contains a "ports" directory with "1"
and "2" in there, but I can't find anything related to my "ib0" and
"ib1" interface in there.
* /sys/class/net/ib0 doesn't seem to contain anything about IB ports either.
