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