Sometimes the MII is not used at all - for example, when the controller is connected to a switch with a fixed speed, and the MDC/MDIO signal are used for something else.

Allow to set a fixed speed in the FEC driver without relying on the autonegotiation.

The use case is the FEC connected to a Switch without using MDIO / MDC. The FEC has no way to get the speed.
