Add switch to perfquery to correctly reset counters on all Infiniband HCAs in RHEL 6
Issue
- According to the manpage of perfquery, -r -a shall reset the counters of all ports, but it only resets the values of the first HCA. "-a, --all_ports show aggregated counters for all ports of the destination lid or reset all counters for all ports.[...]"
- perfquery only resets all counters on the first HCA. Beyond the first HCA, you must specify each additional HCA address in order to reset it's counters.
Environment
- Red Hat Enterprise Linux (RHEL) 6
- Remote Dynamic Memory Access (RMDA)
- infiniband-diags
