 Actually I don't think there are 2 PHYs, in the cubietruck schematics, as
 well as the lime2 schematic, and by board inspection, there is only one
 PHY. I think the same PHY is responding on 2 different addresses.
 
 Also, it looks like the lim2 resision I have and the cubietruck have
 the same 8211 variant.
 
 I'll have to investigate some more on my side then
