Subject: [PATCH 3/3] igb: Use device_set_wakeup_enable

Author: Rafael J. Wysocki <rjw@...k.pl>
Subject: igb: Use device_set_wakeup_enable
 
Since dev->power.should_wakeup bit is used by the PCI core to
decide whether the device should wake up the system from sleep
states, set/unset this bit whenever WOL is enabled/disabled using
igb_set_wol().  Accordingly, use device_can_wakeup() for checking
if wake-up is supported by the device.
