The driver currently does not make use of this feature. Instead, whenever there is a link status change event, it reads the current link parameters from the PHY, and programs those parameters into the mv643xx_eth MAC by hand. This patch switches the mv643xx_eth driver to letting the MAC auto-determine the (R)(G)MII link parameters by PHY polling, if there is a PHY present. For PHYless ports (when e.g. the (R)(G)MII interface is connected to a hardware switch), we keep hardcoding the MII interface parameters.
