+ * Per-lcore variables and lcore launch
+ * ====================================
+ *
+ * - Use ``rte_eal_mp_remote_launch()`` to call ``assign_vars()`` on
+ * every available lcore. In this function, a per-lcore variable is
+ * assigned to the lcore_id.
+ *
+ * - Use ``rte_eal_mp_remote_launch()`` to call ``display_vars()`` on
+ * every available lcore. The function checks that the variable is
+ * correctly set, or returns -1.
+ *
+ * - If at least one per-core variable was not correct, the test function
+ * returns -1.
