---|
| 41 | * Structures defining a network interface, providing a packet |
---|
| 42 | * transport mechanism (ala level 0 of the PUP protocols). |
---|
| 43 | * |
---|
| 44 | * Each interface accepts output datagrams of a specified maximum |
---|
| 45 | * length, and provides higher level routines with input datagrams |
---|
| 46 | * received from its medium. |
---|
| 47 | * |
---|
| 48 | * Output occurs when the routine if_output is called, with three parameters: |
---|
| 49 | * (*ifp->if_output)(ifp, m, dst, rt) |
---|
| 50 | * Here m is the mbuf chain to be sent and dst is the destination address. |
---|
| 51 | * The output routine encapsulates the supplied datagram if necessary, |
---|
| 52 | * and then transmits it on its medium. |
---|
| 53 | * |
---|
| 54 | * On input, each interface unwraps the data received by it, and either |
---|
| 55 | * places it on the input queue of a internetwork datagram routine |
---|
| 56 | * and posts the associated software interrupt, or passes the datagram to a raw |
---|
| 57 | * packet input routine. |
---|
| 58 | * |
---|
| 59 | * Routines exist for locating interfaces by their addresses |
---|
| 60 | * or for locating a interface on a certain network, as well as more general |
---|
| 61 | * routing and gateway routines maintaining information used to locate |
---|
| 62 | * interfaces. These routines live in the files if.c and route.c |
