From my RapsBerry Pi 2 B running Ubuntu 14.04LTS I do:
So the device turns off (nothing on the screen).
If I then try to wake on LAN it up with the usual method:
... nothing happens.
Any other desktop computer on my LAN awakes fine, so I must suppose this is some issue with the drivers.
The eth0 info in the RapsBerry seems correctly configured for wake on LAN:
luis@Zarzamoro:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]

Supported pause frame use: No

As long as the LAN card seems to be Wake on LAN capable, I assume that maybe another distro would be more optimized in ethernet drivers matter and could put the device in wake on LAN state?
For those arguing there is no need(?) to wake on LAN the RapsBerry Pi, consider these scenarios:
- You have a Rapsberry that you would like to go unnoticed (hidden, nobody must know it is there; they could grab it, you know). So you let it off and you start it up (wake on LAN) when desired (only you will know the MAC address).
- You would like to fully stop the network to isolate network traffic in order to sniff LAN data and detect some misbehavior, failure, virus... etc. Going through all the computers/portables/devices to turn them all off is rather awkward. So you order some sort of
poweroff(even massive poweroff by using some .sh script) and, later, you turn them all on again via Wake on LAN (massive method is possible to, for example with
wakeonlantool from Linux).
