111 | * Structures defining a network interface, providing a packet |
112 | * transport mechanism (ala level 0 of the PUP protocols). |
113 | * |
114 | * Each interface accepts output datagrams of a specified maximum |
115 | * length, and provides higher level routines with input datagrams |
116 | * received from its medium. |
117 | * |
118 | * Output occurs when the routine if_output is called, with three parameters: |
119 | * (*ifp->if_output)(ifp, m, dst, rt) |
120 | * Here m is the mbuf chain to be sent and dst is the destination address. |
121 | * The output routine encapsulates the supplied datagram if necessary, |
122 | * and then transmits it on its medium. |
123 | * |
124 | * On input, each interface unwraps the data received by it, and either |
125 | * places it on the input queue of a internetwork datagram routine |
126 | * and posts the associated software interrupt, or passes the datagram to a raw |
127 | * packet input routine. |
128 | * |
129 | * Routines exist for locating interfaces by their addresses |
130 | * or for locating a interface on a certain network, as well as more general |
131 | * routing and gateway routines maintaining information used to locate |
132 | * interfaces. These routines live in the files if.c and route.c |
