Hello,

now the question may seem simple ("how to grab the MAC address of a given interface"), but what is actually a "portable" way that does not potentially break when upgrading to a newer openSUSE?

I could fiddle with `hwinfo --network` or try parse `ip l sh dev br0` output, but what's actually best? [Using sh.]

How about this?

% cat /sys/class/net/eth?/address

eshsf

Or the long version: /sbin/ifconfig [interface] | grep HWaddr | tail --bytes=20 | head --bytes=17 I'm sure that could be rewritten to something less ugly to ignore the last three "empty" bytes. This will work on other dists aswell, where as /sys/class/net/eth?/address does not exists on e.g. debian iirc.
