OK. I replaced the /sys/class/infiniband/qib0/stats file with % ls /sys/class/infiniband/qib0/ports/1/diag_counters/ dmawait pkt_drops rc_dupreq rc_seqnak rnr_naks loop_pkts rc_acks rc_qacks rc_timeouts seq_naks other_naks rc_delayed_comp rc_resends rdma_seq unaligned These are all simple counter values. For the QSFP data, I hope I can leave it as is since it is related to the link state that the other files contain. It is a read-only file so no issue with trying to set a value. -- 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
