If you insist on passing lcore_id around as a function parameter, the function description must mention that the lcore_id parameter must be set to rte_lcore_id() for the functions where this is a requirement, including all functions that use those functions. Alternatively, follow my previous suggestion: Omit the lcore_id function parameter, and use rte_lcore_id() instead.
