203 | * Protocol switch table. |
204 | * |
205 | * Each protocol has a handle initializing one of these structures, |
206 | * which is used for protocol-protocol and system-protocol communication. |
207 | * |
208 | * A protocol is called through the pr_init entry before any other. |
209 | * The system will call the pr_drain entry if it is low on space and this |
210 | * should throw away any non-critical data. |
211 | * |
212 | * Protocols pass data between themselves as chains of mbufs using |
213 | * the pr_input and pr_output hooks. Pr_input passes data up (towards |
214 | * the users) and pr_output passes it down (towards the interfaces); control |
215 | * information passes up and down on pr_ctlinput and pr_ctloutput. |
216 | * The protocol is responsible for the space occupied by any the |
217 | * arguments to these entries and must dispose it. |
218 | * |
219 | * The userreq routine interfaces protocols to the system and is |
220 | * described below. |
221 | * |
222 | * After a protocol is attached, its pr_domain will be set to the domain |
223 | * which the protocol belongs to, and its pr_protosw will be set to the |
224 | * address of the protosw instance. The latter is useful for finding |
225 | * the real/original protosw instance, in the event so_proto is altered |
226 | * to point to an alternative/derivative protosw. E.g. the list of |
227 | * socket filters is only applicable on the original protosw instance. |
