Re: [PATCH 2/4] setup wake-on-lan before shutting down

From: Tobias Diedrich <redacted> 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.
