From bdf0a550c81c293f22bc511e3cd2d0bf1d847d47 Mon Sep 17 00:00:00 2001 From: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com> Date: Thu, 4 Jun 2009 11:09:58 +0000 Subject: [PATCH] ixgbe: Enable ACPI WoL capabilities for 82599 The 82599 KX4 device defaults to legacy power management, or APME. This puts the device into ACPI mode, which allows more robust WoL setups to work properly.
