  The answer to the question
  
  	(Is there a better way to force a parse to fail from arbitrary
  	places in routines called by the parser?)
  
  asked in an earlier checkin is "yes", which would've been obvious had I
  seen the code that handles MAC addresses, as it returns NULL on an
  error, and the YACC clause checks for a null return value and, if the
  return value is null, uses YYERROR to make the parse fail.
  
  Use that for IPv4 and IPv6 errors.
  
  Also, use "dfilter_fail()" for the MAC address code.
