Intercept access to register 31 and store the desired value for each

port

in the driver. When issuing access to other registers add the saved

page.

This given, the hardware will run two consecutive c22 commands that are
not interrupted by polling.

  ... hardware poll ...
  phy_write(phy, 31, page)
  phy_write(phy, reg, value)
  ... hardware poll ...

How do you guarantee the polling will not get between?

The page is part of a single command towards the controller.
If a page is given the hardware will make the above two MDIO 
commands out of this without any polling in between.

I will clarify this in the next version.
