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
