These are needed for some particular port configurations where the default speed isn't suitable for all link speed types. (Ie, changing 10/100/1000MBit PLL rate requires a similar MII clock rate, rather than a fixed MII rate.) This is: * only currently implemented for the ar71xx; * isn't used anywhere (yet), as the final interface for this hasn't yet been determined.
