Ok, thank you - that's good to know, because it means there is something wrong with how my interface is initially brought up. And indeed I found the problem: my startup scripts apparently bring up the interface twice - once to "pre-start" (load/verify modules etc.) and then again after applying mtu/route/etc. settings. Obviously without MTU bringing up the interface will pull in the default qdisc in the interface's default config, and that's what I saw after boot. Weird but what can I say. Anyway, thanks for trying to help. :) Holger
