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
