There are no 32 bit equivalents of those 4 "IETF" counters ([uni
multi]cast [xmit rcv] pkts).
When not supported, perhaps it is best not to populate these counters in
sysfs so one can discern between counter not supported and 0 value.
I'm still working on definitive mthca answer but think the attribute is
not supported there. Does anyone out there have an mthca setup where
they can try this ?
