Most likely, you do not want to use more than one HTB qdisc per device.

What do you need this qdisc for?

> 50kbps ceil 100kbps prio 2

Why not make these children of the first qdisc?

Please don't send HTML mails (or at least include a text-only version).
Otherwise it is really awful to read. Thanks.

What about the example from the HTB User Guide?? Is it wrong?

Ah, you want to simulate a slow link. Didn't realize that, sorry. :-)

Have a look on the output of the tc -s -d class show dev $dev statistics.
Also try qdisc show instead of class show, the direct_packets_stat should 
be zero.

The packets should go into the class 100:1 (you may have to add "default 1" 
or a filter that puts them there). So far you only got one filter for the 
child qdisc, but for that the packets have to get there first.
