3.18-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit c4ce446e33d7a0e978256ac6fea4c80e59d9de5f ]
The driver currently silently accepts unsupported Wake-on-LAN modes (other than WAKE_PHY or WAKE_MAGIC) without reporting that to the user, which is confusing.
