/*
* FIELDS
* qp0_mads_outstanding
* Contains the number of MADs outstanding on QP0.
* When this value reaches zero, OpenSM has discovered all
* nodes on the subnet, and finished retrieving attributes.
* At that time, subnet configuration may begin.
* This variable must be manipulated using atomic instructions.
*
* qp0_mads_outstanding_on_wire
* The number of MADs outstanding on the wire at any moment.
*
* qp0_mads_rcvd
* Total number of QP0 MADs received.
*
* qp0_mads_sent
* Total number of QP0 MADs sent.
*
* qp0_unicasts_sent
* Total number of response-less MADs sent on the wire. This count
* includes getresp(), send() and trap() methods.
*
* qp0_mads_rcvd_unknown
* Total number of unknown QP0 MADs received. This includes
* unrecognized attribute IDs and methods.
*
* sa_mads_outstanding
* Contains the number of SA MADs outstanding on QP1.
*
* sa_mads_rcvd
* Total number of SA MADs received.
*
* sa_mads_sent
* Total number of SA MADs sent.
*
* sa_mads_rcvd_unknown
* Total number of unknown SA MADs received. This includes
* unrecognized attribute IDs and methods.
*
* sa_mads_ignored
* Total number of SA MADs received because SM is not
* master or SM is in first time sweep.
