I have.

Because someone wrote it to do that, a mark of 0xdadface will map to 
flowid dad:face.

I'm pretty sure you are, I have it working here at my end.

The CLASSIFY target of iptables is something I have overlooked, it looks 
like it does exactly the same thing except with a slightly different and 
less obscure syntax.

I'll change my script to use CLASSIFY in stead, it seems a lot nicer.

First the error, it was because I had "handle 1" in there, just like 
Andy said.


The trick is that this:
iptables -t mangle -A to-dsl -s $subnet -j MARK --set-mark $mark

... sets a mark that this:
tc filter add dev $uplink parent 1: protocol ip prio 1 fw

... uses to hit this directly:
tc class add dev $uplink parent 1:1 classid $class htb \
  ceil $userUpCeil rate $userUpRate burst 15k prio 10


Without any inbetween duplication of information, but so does CLASSIFY, 
so I'll just use that later on, thanks.
