axe(4) requires exact link state/speed information from mii(4) to
reprogram controller to resolved speed/duplex. In this case
ukphy(4) seems to report fake link state/speed to axe(4).

This looks like Agere systems ET110C TruePHY. Would you try
attached patch? Because truephy(4) pokes some undocumented PHY
registers on PHY reset I'm not sure this model also requires that
magic to make it work though.
