From 82776a4bcd7aa5fbcd2e6339b3ce88b727dd40ab Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Fri, 14 Aug 2009 14:35:33 +0000 Subject: [PATCH] e1000e: WoL does not work on 82577/82578 with manageability enabled With manageability (Intel AMT) enabled via BIOS, PHY wakeup does not get configured on newer parts which use PHY wakeup vs. MAC wakeup which causes WoL to not work. The driver should configure PHY wakeup whether or not manageability is enabled. Signed-off-by: Bruce Allan Signed-off-by: Jeff Kirsher Signed-off-by: David S.
