(1) for the MPI2_EVENT_IR_OPERATION_STATUS event, add support to print
"background init" or "make data consistent" for debugging purposes.  If the

(2) for the MPI2_EVENT_SAS_DEVICE_STATUS_CHANGE event, add support to print
"expander reduced functionality" and "expander reduced functionality
complete", which are new events.
