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