* Internal validation function. For validating both actions and items. * * @param[in] dev * Pointer to the rte_eth_dev structure. * @param[in] attr * Pointer to the flow attributes. * @param[in] items * Pointer to the list of items. * @param[in] actions * Pointer to the list of actions. * @param[in] external * This flow rule is created by request external to PMD. * @param[in]

 *   0 on success, a negative errno value otherwise and rte_errno is set.
