-tcp_abc - INTEGER
- 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.
- Default: 0 (off)
