I think if you want esqf to do dst filtering, then you should use htb to 
seperate interactive traffic and have just one class for everyones bulk 
traffic with one esqf attached. You are already splitting with htb the ips 
to 10 and 11 then giving them one queue each - they should go to one esqf.

I'm not sure, but shouldn't you use flowid rather than classid in the $tc 
filter add lines.
