87 | * Protocol switch table. | |

89 | * Each protocol has a handle initializing one of these structures, | |
90 | * which is used for protocol-protocol and system-protocol communication. | |
91 | * | |
92 | * A protocol is called through the pr_init entry before any other. | |
93 | * Thereafter it is called every 200ms through the pr_fasttimo entry and | |
94 | * every 500ms through the pr_slowtimo for timer based actions. | |
95 | * The system will call the pr_drain entry if it is low on space and | |
96 | * this should throw away any non-critical data. | |
97 | * | |
98 | * Protocols pass data between themselves as chains of mbufs using | |
99 | * the pr_input and pr_output hooks. Pr_input passes data up (towards | |
9bccf70c | 100 | * the users) and pr_output passes it down (towards the interfaces); control |
1c79356b A |
101 | * information passes up and down on pr_ctlinput and pr_ctloutput. |
102 | * The protocol is responsible for the space occupied by any the | |
103 | * arguments to these entries and must dispose it. | |
104 | * | |
105 | * The userreq routine interfaces protocols to the system and is | |
106 | * described below. | |
