+ Controls Appropriate Byte Count (ABC) defined in RFC3465.
+ ABC is a way of increasing congestion window (cwnd) more slowly
+ in response to partial acknowledgments.
+ Possible values are:
+ 0 increase cwnd once per acknowledgment (no ABC)
+ 1 increase cwnd once per acknowledgment of full sized segment
+ 2 allow increase cwnd by two if acknowledgment is
+ of two segments to compensate for delayed acknowledgments.
