  Modified files:
    sys/netinet          tcp_input.c 
  Log:
  Slight tweak to tcp.blackhole to add optional behaviour to
  drop any segment arriving at a closed port.
  tcp.blackhole=1 - only drop SYN without RST
  tcp.blackhole=2 - drop everything without RST
  tcp.blackhole=0 - always send RST - default behaviour
  
  This confuses nmap -sF or -sX or -sN quite badly.
