  Log:
  SVN rev 205024 on 2010-03-11 17:56:46Z by qingli
  
  The if_tap interface is of IFT_ETHERNET type, but it
  does not set or update the if_link_state variable.
  As such RT_LINK_IS_UP() fails for the if_tap interface.
  
  Also, the RT_LINK_IS_UP() needs to bypass all loopback
  interfaces because loopback interfaces are considered
  up logically as long as the system is running.
  
  This patch fixes the above issues by setting and updating
  the if_link_state variable when the tap interface is
  opened or closed respectively. Similary approach is
  already done in the if_tun device.
