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 ? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
