Collision Test
When set, this bit will cause the COL signal to be asserted in
response to the assertion of TX_EN in internal MII interface.

Link Status
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the link status bit to be
1 = Collision test enabled.
