 peakrate
 Maximum depletion rate of the bucket. Limited to 1mbit/s on Intel, 10mbit/s on Alpha. The peakrate does 
 not need to be set, it is only necessary if perfect millisecond timescale shaping is required.

 mtu/minburst
 Specifies the size of the peakrate bucket. For perfect accuracy, should be set to the MTU of the interface.
 If a peakrate is needed, but some burstiness is acceptable, this size can be raised. A 3000 byte minburst
 allows around 3mbit/s of peakrate, given 1000 byte packets.
