Subject: [PATCH 1/2] r8169: Enable WOL from Magic Packet by default

Set the WOL config registers to only enable WOL from magic packet by
default. Without this change in place, the WOL config register
settings on warm reboot come up in an inconsistent state since these
registers don't get reset on a warm reboot.
