! 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
