At present the link speed change callback is a nop. According to macb device tree bindings, an optional "tx_clk" is used to clock the ethernet controller's TX_CLK under different link speed.
In 10/100 MII mode, transmit logic must be clocked from a free running clock generated by the external PHY. In gigabit GMII mode, the controller, not the external PHY, must generate the 125 MHz transmit clock towards the PHY.
