22 * Structures defining a network interface, providing a packet
23 * transport mechanism (ala level 0 of the PUP protocols).
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
