8.10.13 Receive Long Packet Maximum Length - RLPML (0x5004; R/W)
8.10.14 Receive Filter Control Register - RFCTL (0x5008; R/W)
8.10.15 Multicast Table Array - MTA (0x5200 + 4*n [n=0...127]; R/W)
There is one register per 32 bits of the Multicast Address Table for a total of 128 registers. Software
must mask to the desired bit on reads and supply a 32-bit word on writes. The first bit of the address
used to access the table is set according to the RX_CTRL.MO field.
Note: All accesses to this table must be 32 bit.
Field Bit(s) Initial Value Description
RLPML 13:0 0x2600
