DEPTH
This number is used to decide the congestion state of the output
buffers. If the number of packets in the output queue meets or
exceeds this number, the congestion counter is incremented.
0 = Disables congestion monitoring
1 = The congestion counter increments when the buffer fill
reaches or exceeds 2
2 = The congestion counter increments when the buffer fill
reaches or exceeds 3
……
7 = the congestion counter increments when the buffer fill
reaches 8
8 = Reserved

LEAK_RT
This value is the leak rate for both
the receiver and transmitter
congestion counters. Whenever this time period expires, the
CONG_CTR values for both transmitter (
Transmitter Output Queue Congestion Status Register” on
page 344
) and receiver (
“RapidIO Port x Receiver Input Queue
Congestion Status Register” on page 349
) are decremented by
1.
0 = Leak rate is disabled
1 = Decrement CONG_CTR every 1.28
s
2 = Decrement CONG_CTR every 2*1.28
s = 2.56

...
2047 = Decrement CONG_CTR every 2047*1.28
s = 2.62ms.
