From: Tobias Diedrich <ranma+kernel@tdiedrich.de>
We currently don't signal the kernel we that this device can wake the system. Call device_init_wakeup() to correct this. Without this device_can_wakeup and device_may_wakeup will return incorrect values. Together with the minimized acpi wakeup patch (6/4 ;)), which will follow in the next mail, this really makes wake-on-lan work for me as expected (i.e. "ethtool -s eth0 wol g" is sufficient, no additional magic needed).
