PDUs rx Number of protocol data units received.
bad CRC headers rx Number of bad CRC headers received.
bad CRC payloads rx Number of bad CRC payloads received.
out of seq PDUs rx Number of out-of-sequence PDUs received.
flow control count Flow control count.
last rtt Last Round trip in milliseconds (RT traffic only).
The following arguments are optional:
