From 9417c464ba834ae29982fcd71bc59dc8e734327c Mon Sep 17 00:00:00 2001 From: Andy Gospodarek Date: Sat, 16 Jul 2011 07:31:33 +0000 Subject: [PATCH] ixgbe: only enable WoL for magic packet by default Martin Wilck reported that systems using the ixgbe-driver that were capable of WoL were rebooting almost as soon as they were shut down. This is because the default WoL settings enabled magic packet, broadcast, unicast, and multicast. Other Intel devices seem to use the stored eeprom value for initial WoL capabilities. The 82578DM (e1000e) and 82576 (igb) the devices I looked at had only the magic packet enabled in the eeprom, so that seems appropriate on ixgbe-based devices as well. I set the WoL options on my 82578DM to be the same default as the ixgbe devices (umbg) and saw the same as Martin -- almost as soon as my box shutdown, it booted again. This patch changes the default to only be the magic packet. This is the same as the default for most Intel and non-Intel hardware currently upstream.
