From b4ef0a651227d7ec469539f22a14cac5514ee86e Mon Sep 17 00:00:00 2001
From: Preston Brown <pbrown@redhat.com>
Date: Fri, 14 Sep 2001 19:07:31 +0000
Subject: remove remnants of LinuxConf.  Don't use ifconfig, only /sbin/ip. 
 Use check_device_down from network-functions instead of re-implementation.
