RE: HTB Rate and Prio (continued)

Just tested with 1800kbits as the rate/ceil of the line, with adjustment to
all the rate to match the total rate, but I have the same result, bandwith
seems to be shared just like if there were no qos in place...

I'll do a full round trip of tests today, it must be hidden somewhere :)
