From 41bedc2c3100bf513b3255c73ab4a611ae625000 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 27 Nov 2007 11:02:32 -0800 Subject: [PATCH] sky2: don't use AER routines Using PCIE advanced error recovery stuff creates more user problems than it's worth. The AER stuff depends on MMCONFIG and in many configurations it just doesn't work. Plus it doesn't add any real functionality to the driver. The sky2 driver handles its own errors fine as is.
