Function Documentation

   int rte_node_eth_config (struct rte_node_ethdev_config * cfg, uint16_t cnt, uint16_t nb_graphs)
       Initializes ethdev nodes.

       Parameters
           cfg Array of ethdev config that identifies which port's ethdev_rx and ethdev_tx nodes need to be
           created and queue association.
           cnt Size of cfg array.
           nb_graphs Number of graphs that will be used.

       Returns
           0 on successful initialization, negative otherwise.

   __rte_experimental int rte_node_ethdev_rx_next_update (rte_node_t id, const char * edge_name)
       Update ethdev rx next node.

       Parameters
           id Node id whose edge is to be updated.
           edge_name Name of the next node.

       Returns

           • EINVAL: Either of input parameters are invalid

           • ENOMEM: If memory allocation failed
