ZL50418 hardware provides a full set of statistics counters for each Ethernet port. The CPU accesses these
counters through the CPU interface. All hardware counters are rollover counters. When a counter rolls over, the
CPU is interrupted, so that long-term statistics may be kept. The MAC detects all statistics, except for the delay
exceed discard counter (detected by buffer manager) and the filtering counter (detected by queue manager). The
following is the wrapped signal sent to the CPU through the command block.
