3.16.62-rc1 review patch. If anyone has any objections, please let me know.

commit 9c734b2769a73eea2e9e9767c0e0bf839ff23679 upstream.
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.
