3.18-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit c5cb93e994ffb43b7b3b1ff10b9f928f54574a36 ] 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.
