From eb7700dc0344564b0b9857d1f5e331a0dd629e92 Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Wed, 16 Jun 2010 13:27:05 +0000 Subject: [PATCH] e1000e: fix check for manageability on ICHx/PCH Do not check for all the bits in E1000_FWSM_MODE_MASK when checking for manageability on 82577/82578; only check if iAMT is enabled. Both of the manageability checks (for 82577/82578 and ICHx) must check the firmware valid bit too since the other bits are only valid when the latter is set.
