I understand, but _why_ it is needed is also obvious in this case; I
mean, without the patch "fixed-link" cannot be used.
Other patches may not be as obvious/simple and thus justify and require
more details.
Anyway, I added "Properly handles the case where the PHY is not connected
to the real MDIO bus" would that be ok?
