[ Upstream commit 4217a64e18a1647a0dbc68cb3169a5a06f054ec8 ]
At the moment, PORT_MII is reported in the ethtool ops. This is odd because it is an interface between the MAC and the PHY and no external port. Some network card drivers will overwrite the port to twisted pair or fiber, though. Even worse, the MDI/MDIX setting is only used by ethtool if the port is twisted pair.
Set the port to PORT_TP by default because most PHY drivers are copper ones. If there is fibre support and it is enabled, the PHY driver will set it to PORT_FIBRE.
This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE; except for the genphy fallback driver.
