The integrated PHY's of later RTL8168 network chips report the generic PHYID 0x001cc800 (Realtek OUI, model and revision number both set to zero) and therefore currently the genphy driver is used.
To be able to use the paged version of e.g. phy_write() we need a PHY driver with the read_page and write_page callbacks implemented.
