|
||
| 38 | * Protocol switch table.
|
||
| 39 | *
|
||
| 40 | * Each protocol has a handle initializing one of these structures,
|
||
| 41 | * which is used for protocol-protocol and system-protocol communication.
|
||
| 42 | *
|
||
| 43 | * A protocol is called through the pr_init entry before any other.
|
||
| 44 | * Thereafter it is called every 200ms through the pr_fasttimo entry and
|
||
| 45 | * every 500ms through the pr_slowtimo for timer based actions.
|
||
| 46 | * The system will call the pr_drain entry if it is low on space and
|
||
| 47 | * this should throw away any non-critical data.
|
||
| 48 | *
|
||
| 49 | * Protocols pass data between themselves as chains of mbufs using
|
||
| 50 | * the pr_input and pr_output hooks. Pr_input passes data up (towards
|
||
| 51 | * UNIX) and pr_output passes it down (towards the imps); control
|
||
| 52 | * information passes up and down on pr_ctlinput and pr_ctloutput.
|
||
| 53 | * The protocol is responsible for the space occupied by any the
|
||
| 54 | * arguments to these entries and must dispose it.
|
||
| 55 | *
|
||
| 56 | * The userreq routine interfaces protocols to the system and is
|
||
| 57 | * described below.
