  Log:
  Implement support for RFC 3514 (The Security Flag in the IPv4 Header).
  (See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)
  
  This fulfills the host requirements for userland support by
  way of the setsockopt() IP_EVIL_INTENT message.
  
  There are three sysctl tunables provided to govern system behavior.
  
          net.inet.ip.rfc3514:
  
                  Enables support for rfc3514.  As this is an
                  Informational RFC and support is not yet widespread
                  this option is disabled by default.
  
          net.inet.ip.hear_no_evil
  
                   If set the host will discard all received evil packets.
  
          net.inet.ip.speak_no_evil
  
                  If set the host will discard all transmitted evil packets.
  
  The IP statistics counter 'ips_evil' (available via 'netstat') provides
  information on the number of 'evil' packets recieved.
  
  For reference, the '-E' option to 'ping' has been provided to demonstrate
  and test the implementation.
