I got a problem while use non-block tcp.
while a netconn_connect invoked,and tcpip_apimsg is called.
if the server replys syn-ack packet after op_completed been post but before msg->err passed to conn->err,the conn state will be err_inprocess instead of err_ok.
so the result is connection is created,but no data can be transmitted because of the err code.
