===================Here is a sample of  htb tcng script and the output:

I thought that it is required:
tc qdisc add dev eth0 handle 2:0 parent 1:0 htb default 5 r2q 100
					        ~~~~~~~
- Jacob

dev "eth0" {
egress { 
    $base = 100 * 1kBps;

    class (<$cl1_2>)  if ((raw[6] & 0xfe) = 0);
    class (<$cl1_12>) if (raw[6] = 2);
    class (<$cl1_10>) if (raw[6] = 0);
    class (<$cl1_11>) if (raw[6] = 1);

    
    htb (r2q 100) {
    	class(rate 10 * $base) {
	$cl1_2 =  class (rate  4 * $base, ceil 8 * $base,)  {
		$cl1_10 = class (rate  3 * $base, ceil 10 * $base, prio 1)  { fifo(limit 8p); }
		$cl1_11 = class (rate  1 * $base, ceil 10 * $base, prio 0)  { fifo(limit 8p); }
        	  }
    	}
	$cl1_12 = class (rate  6 * $base, ceil 10 * $base, prio 1, default) { fifo(limit 8p); }
    }
}
}
