4.18-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit c530c471ba37bdd9fe1c7185b01455c00ae606fb ]
The driver does not check for Wake-on-LAN modes specified by an user, but will conditionally set the device as wake-up enabled or not based on that, which could be a very confusing user experience.
