In these cases, the PHY_DETECT bit indicates link status. This results in forcing the MAC state whenever the PHY link goes down which is not intended. As a side effect, LED's configured to show link status stay lit even though the physical link is down. Add a check in mac_link_down and mac_link_up to see if it concerns an external port and only then, look at PPU status.
