[ Upstream commit 9ee09edc05f20422e7ced84b1f8a5d3359926ac8 ]
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.
