//
// This module implements a Two Rate Three Color Meter (RFC 2698).
//
// It classifies IP packets based on two rates, Peak Information Rate (PIR)
// and Committed Information Rate (CIR), and their associated burst sizes
// to be either green, yellow or red.
//
// The green traffic is guaranteed to be under (in bits)
//   pir * (t1 - t0) + 8 * pbs and cir * (t1 - t0) + 8 * cbs,
// and yellow traffic to be under
//   pir * (t1 - t0) + 8 * pbs
// in every [t0,t1] interval.
//
// When operating in color-aware mode, the meter does not recolor
// a packet that was colored by a previous marker to a lesser
// conforming color.
