[PATCH net v2 6/7] smsc75xx: Check for Wake-on-LAN modes
From: Florian Fainelli <f.fainelli@gmail.com>

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: 6c636503260d ("smsc75xx: add wol magic packet support")
