commit 3364c49be216e4dcc309c935d03deaf710d82513
Author: Hannes Reinecke <hare@suse.de>
Date:   Wed Mar 17 14:01:13 2010 +0100

Add 'fcoe-setup.sh' script in contrib
    
    Add an fcoe-setup.sh script which creates and configures
    a VLAN for FCoE. It also creates the required config file
    for SUSE so that the interface will be started automatically
    on next reboot.
