   54  * This interface must manage two items concerning remote procedure calling:
   55  *
   56  * 1) An arbitrary number of transport connections upon which rpc requests
   57  * are received.  The two most notable transports are TCP and UDP;  they are
   58  * created and registered by routines in svc_tcp.c and svc_udp.c, respectively;
   59  * they in turn call xprt_register and xprt_unregister.
   60  *
   61  * 2) An arbitrary number of locally registered services.  Services are
   62  * described by the following four data: program number, version number,
   63  * "service dispatch" function, a transport handle, and a boolean that
   64  * indicates whether or not the exported program should be registered with a
   65  * local binder service;  if true the program's number and version and the
   66  * port number from the transport handle are registered with the binder.
   67  * These data are registered with the rpc svc system via svc_register.
   68  *
   69  * A service's dispatch function is called whenever an rpc request comes in
   70  * on a transport.  The request's program and version numbers must match
   71  * those of the registered service.  The dispatch function is passed two
   72  * parameters, struct svc_req * and SVCXPRT *, defined below.
