[PATCH net v2 3/7] lan78xx: Check for supported Wake-on-LAN modes

[Florian Fainelli <f.fainelli@gmail.com>]

The driver supports a fair amount of Wake-on-LAN modes, but is not
checking that the user specified one that is supported.

Fixes: 55d7de9de6c3 ("Microchip's LAN7800 family USB 2/3 to 10/100/1000 Ethernet device driver")
