total_rx_error contains the total number of receive errors on
circuit cct. This value equals the sum of bad_frames_rx,
frams_incomp_rx, frmr_frames_rx, lack_resc_error_rx,
oflo_rx, rejects_rx, and runts_tx.
total_tx_error contains the total number of transmission errors,
which is the sum of uflo_tx, latency_tx, and tx_congestion.
tx_congestion contains the total number of packets dropped due to
congestion, which is the sum of hipri_congestion, normpri_con-
gestion, and lowpri_congestion.
tx_peak_rate contains the peak data transmission rate in bits per
second.
tx_queue_len contains the number of octets (of all priorities)
currently queued to the circuit. This statistic is used as a parameter for
controlling latency when Max Link Latency is configured for the circuit.
tx_rate contains the current data transmission rate in bits per
second.
uflo_tx contains the total number of underflows on circuit cct. An
underflow occurs when the transmitter portion of the link level control-
ler truncates a frame because of late receipt of data from memory.
xmt_desc_cnt contains the current number of frames awaiting
transmission by the link level controller.
