Details:

Hi all:
      I use the new version from cvs.but find when use tcp connect,only two
handshake,SYN->SYN+ACK,not send ACK,I change the tcp_process function as
follow:

tcp_process(struct tcp_pcb *pcb)
{
...

switch (pcb->state)
{
  case SYN_SENT:
       ...
       tcp_ack(pcb);
       ...
       break;
  case SYN_RCD:
       ...

}

I change "tcp_ack(pcb)" to "tcp_ack_now(pcb)",it can generate three
handshake,do you agree?
}
