 * "service dispatch" function, a transport handle, and a boolean that
 * indicates whether or not the exported program should be registered with a
 * local binder service;  if true the program's number and version and the
 * port number from the transport handle are registered with the binder.
 * These data are registered with the rpc svc system via svc_register.
 *
 * A service's dispatch function is called whenever an rpc request comes in
 * on a transport.  The request's program and version numbers must match
