No, no I'm not, I'm using iptables like this:

...
iptables -t mangle -A from-dsl-eth1 -d 10.48.6.0/24 -j MARK --set-mark 
0x14806
iptables -t mangle -A from-dsl-eth1 -d 10.48.6.0/24 -j RETURN
tc class add dev eth1 parent 1:1 classid 1:4806 htb rate 1200mbit burst 
15k prio 10
tc qdisc add dev eth1 parent 1:4806 sfq perturb 21
...

That means that packets with --set-mark 0x14806 get put into classid 1:4806

The RETURN rule means that I can have a -j LOG at the end of my chain to 
figure out what didn't get matched, I just wish you could say -j 
MARK,RETURN in the same rule.

The funny thing that I realized after sending the original mail is that 
the shaper works, it classifies the traffic correctly, eventhough the tc 
filter command moans about an invalid argument.


It would be very nice to either get a usable error message or have tc 
shut up about the non-error.
