Automatic detection and configuration of network cards

Hello everyone! Is there any possibility that autoyast automatically uses the detected network cards without explicitely giving any information in the control file? The problem is, that I have one normal (100 Mbit) Card with Intel-Chipset (Module: e100) and one Gigabit-Card (e1000), but the device names may differ. Sometimes eth0 is Gigabit, sometimes eth1. So, if I give static information in the contol file, I have a problem... Another point is, that autoyast detects the cards correctly, but they appear as 'unconfigured' when I invoke yast2 after installation. Any hints? Regards, Martin
