># It's a list of devices and maximum bandwidth in kbit.
># For example, the german TDSL account, provides 128kbit/s upstream
># and 768kbit/s downstream. We can only tune the upstream.
>#
># Example:
># If you want to tune a 128kbit/s upstream DSL device like german TDSL set
># the following values:
># FW_HTB_TUNE_DEV="dsl0,125"
># where dsl0 is your pppoe device and 125 stands for 125kbit/s upstream
>#
># you might wonder why 125kbit/s and not 128kbit/s. Well practically you'll
># get a better performance if you keep the value a few percent under your
># real maximum upload bandwidth, to prevent the DSL modem from queuing traffic in
># it's own buffers because queing is done by us now.
># So for a 256kbit upstream
>#   FW_HTB_TUNE_DEV="dsl0,250"
># might be a better value than "dsl0,256". There is no perfect value for a
># special kind of modem. The perfect value depends on what kind of traffic you
># have on your line but 5% under your maximum upstream might be a good start.
># Everthing else is special fine tuning.
