In the old and new network stack, you can start a telnet server like this:

static void
telnet_shell(char *name, void *arg)
{
	rtems_shell_env_t env;

	memset(&env, 0, sizeof(env));

	env.devname = name;
	env.taskname = "TLNT";
	env.login_check = NULL;
	env.forever = false;

	rtems_shell_main_loop(&env);
}

rtems_telnetd_config_table rtems_telnetd_config = {
	.command = telnet_shell,
	.arg = NULL,
	.priority = 0,
	.stack_size = 0,
	.login_check = NULL,
	.keep_stdio = false
};

static void
test_main(void)
{
	rtems_status_code sc = rtems_telnetd_initialize();
	assert(sc == RTEMS_SUCCESSFUL);

	rtems_task_delete(RTEMS_SELF);
	assert(0);
}

In libbsd you can also use the rc.conf approach described by Chris.

   /**
    * @brief Task priority.
    *
    * Use 0 for the default value.
    */
   rtems_task_priority priority;

So, this is an RTEMS priority.
