  * Output occurs when the routine if_output is called, with three parameters:
- *	(*ifp->if_output)(ifp, m, dst, rt)
+ *	(*ifp->if_output)(ifp, m, dst, ro)
  * Here m is the mbuf chain to be sent and dst is the destination address.
  * The output routine encapsulates the supplied datagram if necessary,
