Parameters node pointer to the rte_rib6_node Returns pointer to the ext int rte_rib6_get_nh (const struct rte_rib6_node * node, uint64_t * nh) Get nexthop from the rte_rib6_node Parameters node pointer to the rib6 node nh pointer to the nexthop to save Returns 0 on success -1 on failure, with rte_errno indicating reason for fail- ure. int rte_rib6_set_nh (struct rte_rib6_node * node, uint64_t nh) Set nexthop into the rte_rib6_node Parameters node pointer to the rib6 node nh nexthop value to set to the rib6 node Returns 0 on success -1 on failure, with rte_errno indicating reason for fail- ure. void rte_rib6_free (struct rte_rib6 * rib) Free an RIB object. Parameters rib RIB object handle created with rte_rib6_create(). If rib is NULL, no operation is performed. struct rte_rib6 * rte_rib6_create (const char * name, int socket_id, const struct rte_rib6_conf * conf) Create RIB Parameters name RIB name socket_id NUMA socket ID for RIB table memory allocation conf Structure containing the configuration Returns Pointer to RIB object on success NULL otherwise with rte_errno indicat- ing reason for failure. struct rte_rib6 struct rte_rib6 * rte_rib6_find_existing (const char * name) Find an existing RIB object and return a pointer to it. Parameters name Name of the rib object as passed to rte_rib6_create() Returns Pointer to RIB object on success NULL otherwise with rte_errno indicat- ing reason for failure.
