    sys/net              if.c 
  Log:
  Initialize the if_addr mutex in if_alloc() rather than waiting until
  if_attach().  This allows ethernet drivers to use it in their routines
  to program their MAC filters before ether_ifattach() is called (de(4) is
  one such driver).  Also, the if_addr mutex is destroyed in if_free()
  rather than if_detach(), so there was another potential bug in that a
  driver that failed during attach and called if_free() without having
  called ether_ifattach() would have tried to destroy an uninitialized mutex.
