As I remember netbsd driver was wrotten for older version of dwc implemented
in allwinners. Is Amlogic version is also old ? As you said before it works,
that means version is not too old, and better idea here is to implement missing
bits for our dwc(4) (as it really good driver and works perfect for SOCKIT).

We can use mii_mediachg() or mii_pollstat() depending on version of hardware.
(although there should be an easiest solution for this problem).
