zhanghongyu 746d68916f net/tcp: add support for the CLOSE_WAIT state 
CLOSE-WAIT - represents waiting for a connection termination request
             from the local user.
      TCP A                                                TCP B

  1.  ESTABLISHED                                          ESTABLISHED
  2.  (Close)
      FIN-WAIT-1  --> <SEQ=100><ACK=300><CTL=FIN,ACK>  --> CLOSE-WAIT
  3.  FIN-WAIT-2  <-- <SEQ=300><ACK=101><CTL=ACK>      <-- CLOSE-WAIT
  4.                                                       (Close)
      TIME-WAIT   <-- <SEQ=300><ACK=101><CTL=FIN,ACK>  <-- LAST-ACK
  5.  TIME-WAIT   --> <SEQ=101><ACK=301><CTL=ACK>      --> CLOSED
  6.  (2 MSL)
      CLOSED

in the current state, we can continue to send data until the user
calls shutdown or close, then directly enter the TCP_LAST_ACK state
