    kernel - MPSAFE the protocol drain routines
    
    * The ip fragment drain was not MPSAFE at all.  Use a token to protect
      the ipq[] queues.
    
    * The tcp reassembly code was only partially MPSAFE due to being
      per-cpu.  Finish it up.  Use atomic ops for the tcp_reass_qsize
      global.
    
    * Add port assertions in the TCP input and output paths.  If we
      are not in the correct thread we panic, period.
    
    * Code cleanup.
