  Log:
  SVN rev 191418 on 2009-04-23 11:51:53Z by rwatson
  
  During if_detach(), invoke if_dead() to set the ifnet's function
  pointers to "dead" implementations that no-op rather than invoking
  the device driver.  This would generally be unexpected and
  possibly quite badly handled by most device drivers after
  if_detach() has completed.
