AFP:
This is the primary Individual Address, used in the recognition of Wake-up frames, as the
source address for transmit pause frames, and may be optionally used to qualify receive pause
frames.
This is a secondary MAC address that may be optionally used to qualify receive pause frames
These secondary addresses are only used for qualifying the destination addresses of receive
frames.
These locations are not implemented
This address is used as the destination address of transmit pause frames
This block comprises the hash table used for qualifying the destination of receive frames.

Address Filter Pointer. The Address Filter Pointer controls
access to a block of storage which is used to hold MAC
addresses, and the destination address hash table. The
pointer defines which set of address match functions are
visible to the Host at offset 0x0050 through 0x005F.
