Parameter
queue-id: Outbound queue ID, in the range of 0 to 7
green-min-threshhold: Minimum queue length to trigger random green packet
dropping, in the range of 0 to 65535. It must be a multiple of 256 bytes.
green-max-threshhold: Queue length to trigger complete green packet dropping,
in the range of 0 to 65535. It must be a multiple of 256 bytes.
green-max-prob: Maximum drop probability for green packets, in the range of 1
to 15.
yellow-min-threshhold: Minimum queue length to trigger random yellow packet
dropping, in the range of 0 to 65535. It must be a multiple of 256 bytes.
yellow-max-threshhold: Queue length to trigger complete yellow packet dropping,
in the range of 0 to 65535. It must be a multiple of 256 bytes.
yellow-max-prob: Maximum drop probability for yellow packets, in the range of 1
to 15.
red-min-threshhold: Minimum queue length to trigger random red packet
dropping, in the range of 0 to 65535. It must be a multiple of 256 bytes.
red-max-threshhold: Queue length to trigger complete red packet dropping, in the
range of 0 to 65535. It must be a multiple of 256 bytes.
red-max-prob: Maximum drop probability for green packets, in the range of 1 to
15.
exponent: Weight for calculating average queue length, in the range of 1 to 15.
