 Two rate three color marker as described on RFC 2698.

 .It Dv NG_CAR_RED
-Alike to NG_CAR_SINGLE_RATE, but with different understanding of extended burst.
-When normal burst exceeded and extended burst is used, packets are counted red with 
-probability equal to part of extended burst consumed. Extended burst getting refilled first. 
-When it is full, committed burst getting refilled. This behavior is alike to RED 
-active queue management algorithm.

 This algorithm is more polite to the TCP traffic then NG_CAR_SINGLE_RATE.

-Committed burst packets are counted as green, exceeding packets are delayed

+Committed burst packets are counted as green, exceeding packets are delayed
