  Log:
  SVN rev 185963 on 2008-12-12 01:36:50Z by csjp
  
  Consider processes attaching/detaching from tun(4) devices as being link
  state changes.  This change modifies tunopen and tunclose to call the
  if_link_state_change() function.  Among other things, this will result in
  devd(8) receiving events from devctl(4) for linkup/link down.  This allows
  us to do several useful things, including initializing tunnel parameters
  and adding routes.
