This was tested with the b53 switch driver which is currently on its way to mainline. +If the internal PHY is not used, b44 will now search on the MDIO bus +for a phy and use the Linux phylib subsystem to register a driver. +Support for the internal PHY must stay here, because there are some +device which are suing the internal phy. + With this patch we scan the mdio bus when the sprom or nvram says that the PHY address is 30, if a PHY was found at this address b44 uses it.
