I could do that but for a class C lan I would have to create 256 
seperate classes and 256 separate filters. Each for every ip. Whereas in 
SFQ you only have to specify that the hashing algorithm should work on 
the dst field & 0xFF and everything works automatically. For more than 
256 ips things will get really clattered. Also I wonder if speed is an 
issue here with so many rules.

I haven't heard about fq_codel. I will give it a look.

Thanks for the suggestions.
