Richard Scheffenegger ad7a0eb189 TCP Cubic: recalculate cwnd for every ACK.
Since cubic calculates cwnd based on absolute
time, retaining RFC3465 (ABC) once-per-window updates
can lead to dramatic changes of cwnd in the convex
region. Updating cwnd for each incoming ack minimizes
this delta, preventing unintentional line-rate bursts.
