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