Subject: [PATCH net 7/7] smsc95xx: Check for Wake-on-LAN modes

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.

Fixes: e0e474a83c18 ("smsc95xx: add wol magic packet support")
