    sys/net/altq         altq_subr.c 
  Log:
  When ALTQ was detached from an interface queue, the function pointers
  for enqueue, dequeue and request ops where reset to NULL. That was fine
  in the old days when ifq_* checked wether ALTQ is enabled and fell back
  to the classic implementation, but now it just deferences a NULL pointer.
  Introduce a new function ifq_set_classic, which resets the pointers to
  the same values if_attach initially uses and which implements the
  classic BSD queueing. Use this in altq_detach and if_attach.
