+ The MDIO bus clock that must be output by the MDIO bus hardware, if

+
+ MDC rate is feed by an external clock (fixed 100MHz) and is divider
+ internally. The default divider is /256 resulting in the default rate
+ applied of 390KHz.
+
+ To follow 802.3 standard that instruct up to 2.5MHz by default, if
