No. For each ethX, the hwloc "ethX" object will only get a Port number if the corresponding sysfs device has some infiniband "child". Otherwise, no Port attribute is added. > I.e., is the dev_id/port number irrelevant if it's not an OpenFabrics device? dev_id seems to be very rarely used outside of IB. It will be 0x0 is the vast majority of cases. With the first patch, we would get Port=1 is most cases. And Port=1, 2, ... for other cases where dev_id is actually used for "shared NICs". It's not too bad. Brice
