|
| 102 |
* Each interface accepts output datagrams of a specified maximum

|
| 105 |

* (*ifp->if_output)(ifp, m, dst, rt)
|
| 108 |
* Here m is the mbuf chain to be sent and dst is the destination address.

* The output routine encapsulates the supplied datagram if necessary,
|
| 110 |
* and then transmits it on its medium.
|
| 111 |
*
|
| 112 |
* On input, each interface unwraps the data received by it, and either
|
| 113 |
* places it on the input queue of a internetwork datagram routine
|
| 114 |
* and posts the associated software interrupt, or passes the datagram to a raw
