From 5f01607a5b5c8781ed5d5deae213b4f01283dba2 Mon Sep 17 00:00:00 2001 From: Jeff Kirsher Date: Wed, 27 Sep 2006 12:53:42 -0700 Subject: [PATCH] e1000: Fix MANC detection for PCIE adapters Several manageability capability detection parts hinted towards our code being incomplete for PCI-E. According to spec, we do not want to poke any MANC bits at all.
