That is not entirely correct.  There is an output queue, and pfifo_fast
is the default (see the LARTC Howto, 9.2.1.1).  But you are right when
you say you need something to slow down the data;the simplest  choice
should be addingthe Token Bucket Filter (9.2.2.2).  

But if the wondershaper already does it all, then it's probably better
to go with it... :)
