Subject: [net-next PATCH 1/6] ixgbe: Enable ACPI WoL capabilities for 82599
Date: Thu, 04 Jun 2009 14:09:58 -0700 [thread overview]
Message-ID: <20090604210941.5011.31995.stgit@localhost.localdomain> (raw)
From: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@intel.com>
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.
