BITS
31:0
Dropped Count
These bits count the number of dropped packets received on Port 2 and is
cleared when read.
Note:
Buffer Manager Port 2 Ingress Rate Drop Count Register (BM_RATE_DRP_CNT_SRC_2)
This register counts the number of packets received on Port 2 that were dropped by the Buffer
Manager due to ingress rate limit discarding (Red and random Yellow dropping).
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 481 hours.
