    _______________________________________________________

Details:

If we see tcp_process() function

  switch (pcb->state) {
  case SYN_SENT:

....
      pcb->cwnd = pcb->mss;
....
      tcp_parseopt(pcb);

tcp_parseopt() sets pcb->mss to the new value.
I think the order should be reversed.

      tcp_parseopt(pcb);
....
      pcb->cwnd = pcb->mss;
