  Log:
  Fix a race condition in detach path of Ethernet devices. Most current
  drivers do something like this:
  
  XX_stop();
  ether_ifdetach();
  
  /* continue and assume device is dead now */
  
  This doesn't work in many cases if a BPF user is left and IFF_PROMISC is
  active, because bpfdetach does a reset of the timer for many drivers.
  The fix is to move the call to if_down into ether_ifdetach, which gives
  the expected behaviour.
