Some Wake-on-LAN modes such as WAKE_FILTER may only be supported by the MAC, while others might be only supported by the PHY. Make sure that the .get_wol() returns the union of both rather than only that of the PHY if the PHY supports Wake-on-LAN. When disabling Wake-on-LAN, make sure that this is done at both the PHY and MAC level, rather than doing an early return from the PHY driver.
