[Sorry, I wasn't paying attention and sent my original reply to the
poster instead of the list]

The filter I sent ought to direct traffic into wondershaper's "bulk"
class, on line 71, which is:

tc class add $DEV parent 1:1 classid 1:30 htb rate $[8*$UPLINK/10]kbit \
   burst 6k prio 2

As you can see, the rate is eight tenths the speed of $UPLINK. Since
there is no ceiling specified, however, it is allowed to "borrow"
bandwidth up to the speed of its parent, which is $UPLINK. If you want
to change the behavior of this class, read how here:
