Hi,

I noticed a couple of drivers implement both the mii and mdiobus 
options, I was pondering why is that. Is there some legacy backward 
compatibility reason for keeping both or is it safe to remove the mii 
support completely from the driver?

Either way, I will do that in a separate patch, so it could be reverted 
if it breaks something.
