RX Multicast
Count of good packets (proper length and free of errors), including MAC
control frames, that have a multicast destination address (not including
broadcasts).
Note:
Port x MAC Receive Multicast Count Register (MAC_RX_MULCST_CNT_x)
This register provides a counter of valid received packets with a multicast destination address. The
counter is cleared upon being read.
Note: A bad packet is one that has a FCS or Symbol error.
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 481 hours.
