A simple ingress shaping on ppp0 (PPPOE DSL line). I want to replace my old 
imq ingress shaper in favor of ifb. My former script used iptables marks  to 
classify the packets. My iptables marks are getting set, as like before with 
imq. But tc seems not to recognize them: It only uses the default class.

So i run tcpdump -i ifb0  and discovered that the packets seems to be still 
encapsulated on ifb0. I suppose this is why my iptables stuff is not working.

I've attached the ingress part of my shaping script. 

Thanks for your help
Frithjof
