From 6ff68026f4757d68461b7fbeca5c944e1f5f8b44 Mon Sep 17 00:00:00 2001 From: "\\\"Rafael J. Wysocki\\" Date: Wed, 12 Nov 2008 09:52:32 +0000 Subject: e1000e: 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 e1000_set_wol(). Accordingly, use device_can_wakeup() for checking if wake-up is supported by the device. Signed-off-by: "Rafael J. Wysocki" Signed-off-by: Jeff Kirsher Signed-off-by: David S.
