DESCRIPTION This API controls the MV device MAC multicast support. The MV
device supports multicast using two tables:
1. Special Multicast Table for MAC addresses of the form 0x01-
00-5E-00-00-XX (where XX is between 0x00 and 0xFF). The
MAC DA[7:0] bits are used as a pointer to the Special Multicast
Table entries in the DA-Filter table. In this case, the function
calls ethPortSmcAddr() routine to set the Special Multicast
Table.
2. Other Multicast Table for multicast of another type. A CRC-
8bit is used as an index to the Other Multicast Table entries in
the DA-Filter table. In this case, the function calculates the
CRC-8bit value and calls ethPortOmcAddr() routine to set
the Other Multicast Table.
