[netdrvr] forcedeth: setup wake-on-lan before shutting down
Tobias Diedrich [Sun, 18 May 2008 13:02:37 +0000 (15:02 +0200)]
When hibernating in 'shutdown' mode, after saving the image the suspend hook
is not called again.
However, if the device is in promiscous mode, wake-on-lan will not work.
This adds a shutdown hook to setup wake-on-lan before the final shutdown.
