Subject: [PATCH 4.9 023/171] sr9800: Check for supported Wake-on-LAN modes
4.9-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.
