We should probably add the original netif name to the generated rule, like: KERNEL=="eth*", so we can have both rules at the same time. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Better change the kernel code to create a wlan* and eth* interface, and I can make udev to handle that properly. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There is no such rule that all wireless driver should have 'wlan%d'", we just need an easy way to distinguish the both, because having two netif's with the same name prefix and the same MAC is just broken in so many ways. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Thanks! Here is a new persistent network rule generator script. Delete the, for duplicated MAC addresses broken, rules: /etc/udev/rules.d/70-persistent-net.rules Replace /lib/udev/write_net_rules with the attached file. Reboot, or run: udevadm trigger --subsystem-match=net and look at: /sys/class/net/ and the re-generated rules file. Thanks again for your patience. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
