   22:  * Structures defining a network interface, providing a packet

   24:  *
   25:  * Each interface accepts output datagrams of a specified maximum
   26:  * length, and provides higher level routines with input datagrams
   27:  * received from its medium.
   28:  *
   29:  * Output occurs when the routine if_output is called, with three parameters:
   30:  *	(*ifp->if_output)(ifp, m, dst)
   31:  * Here m is the mbuf chain to be sent and dst is the destination address.
   32:  * The output routine encapsulates the supplied datagram if necessary,
   33:  * and then transmits it on its medium.
   34:  *
   35:  * On input, each interface unwraps the data received by it, and either
   36:  * places it on the input queue of a internetwork datagram routine
   37:  * and posts the associated software interrupt, or passes the datagram to a raw
   38:  * packet input routine.
   39:  *
   40:  * Routines exist for locating interfaces by their addresses
   41:  * or for locating a interface on a certain network, as well as more general
   42:  * routing and gateway routines maintaining information used to locate
   43:  * interfaces.  These routines live in the files if.c and route.c
