Merge branch 'net-usb-Check-for-Wake-on-LAN-modes'

Florian Fainelli says:

====================
net: usb: Check for Wake-on-LAN modes

Most of our USB Ethernet drivers don't seem to be checking properly
whether the user is supplying a correct Wake-on-LAN mode to enter, so
the experience as an user could be confusing, since it would generally
lead to either no wake-up, or the device not being marked for wake-up.

Please review!

Changes in v2:

- fixed lan78xx handling, thanks Woojung!
