Description: An entry in the WRED congestion avoidance curve profile table.

Congestion avoidance allows frames to be dropped during congestion

before they are enqueued (thus avoiding further congestion).

The RCOLOR of a frame as it arrives at the egress enqueuing stage

determines which WRED curve of the congestion avoidance profile

to use (Green or Yellow). A congestion profile has two configurable

WRED curves (Curve-1 and Curve-2). By default Green frames map

to Curve-1 and Yellow frames map to Curve-2.

If no congestion avoidance profile is referenced by a queue within a

queue group, this signifies that no congestion avoidance is in

effect (Tail Drop) and frames are enqueued only if there is space

in the queue; otherwise they are dropped.
