[LARTC] wondershaper HTB thoughts

Hi, 

I've just started using wondershaper (HTB version) and I had a few thoughts
(probably mostly as I'm new to this):

a) there is a filter to add stuff into the 1:20 class, however that's the
default so surely this is pointless.

b) there is no ceil specified for the queues. According to the HTB
documentation, this will prevent the queues sharing bandwidth. Wouldn't
adding "ceil ${UPLINK}kbit" be a good idea?

c) an ingress filter is setup to drop packets arriving faster than "a bit
less than the max speed" in order to prevent large queues building up at the
ISP.  I don't see how this helps at all - surely this only slows traffic -
why would the queues get smaller?  Our ISP would (I'd have thought) buffer a
fixed amount - which will now take longer to get through.

Surely what we might want to do is to put an ingress limit on "bulk"
traffic. i.e. if our inbound is 30kbps max, have a root limit of 40kbps
(which we won't ever reach), then give bulk traffic a rate of 25kbps with a
ceil of 30kbps.

BTW I've just rolled iproute packages for debian with htb3.6 if anyone is
interested (just email me privately).
