This sounds like a good idea, but I have problems to implement.

How I would like the logic to be:

- in dev.nut "PHY_MODE_MII" should not be provided and not be defined for
  all archs beside AT91.
- for any arch, if "PHY_MODE_MII" is defined in the .conf file,
  PHY_MODE_MII should be provided and be defined for
  all archs beside AT91.
- "PHY_MODE_MII" should be provided and defined with AT91 when
  PHY_MODE_RMII" is not given in the conf file.
- For AT91, with "PHY_MODE_RMII" defined in the .conf file, "PHY_MODE_MII"
  should not be provided and not be defined.

Bye
