Log:
  MFC r184097:
  
    Update a comment which to my reading had been misplaced in rev. 1.12
    already (but probably had been way above as the code was there twice)
    and describe what was last changed in rev. 1.199 there (which now is
    in sync with in6_src.c r184096(HEAD), r189956(stable/7)).
