    We add a IMMED data area (16 bytes by default) in
    packet header which will contains as much origin
    data as possible. If origin can put all data in
    packet header, then it no longer needs to send
    separate data packet. When target recieves the
    packet header, it will first copy data out from
    the IMMED data area. If there is still more
    data coming, it continues to receive following
    packets; if all data is included in header, then
    recieving is done.
