cleared when read.
Note:
Switch Engine Port 0 Learn Discard Count Register (SWE_LRN_DISCRD_CNT_MII)
This register counts the number of MAC addresses on Port 0(Host MAC) that were not learned or were
overwritten by a different address due to address table space limitations.
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 481 hours.
