From 25d90810ff49d2a63475776f24c74c6bb49b045f Mon Sep 17 00:00:00 2001 From: Tobias Diedrich Date: Sun, 18 May 2008 15:04:29 +0200 Subject: [PATCH] [netdrvr] forcedeth: reorder suspend/resume code Match the suspend/resume code ordering in e100/e1000e more closely. For example the configuration space should be saved on suspend even for devices that are not up.
