The pins are input signals during reset and are latched at the end of reset to
select hashing algorithm. HASH_MODE[0] is full duplex LED of port 0 after
reset if LED direct mode is selected. HASH_MODE[1] is link LED of port 7 after
reset if LED direct mode is selected.
Aging time selection of address table
An address tag in hashing table will be removed if this function is turned on and
its aging timer expires.
