73.4.2 TRTCM - Color-aware Mode

In color-aware mode the evaluation of the packets uses the existing packet loss priority. TRTCM can
increase a packet loss priority of a packet but it cannot decrease it. Packets that have been previously
marked red or yellow can only be marked with an equal or higher packet loss priority.
Packets marked red (High packet loss priority) continue to be red without evaluation against the PIR or
CIR. Packets marked yellow can only be marked red or remain yellow so they are only evaluated
against the PIR. Only the packets marked green are first evaluated against the PIR and then if they don't
exceed the PIR level, they will be evaluated against the CIR.
