The existing rte_event_eth_rx_adapter_queue_add() API supports adding multiple queues by specifying rx_queue_id = -1, but it lacks the ability to apply specific configurations to each of the added queues. The proposed API, rte_event_eth_rx_adapter_queues_add, addresses this limitation by: - Enabling users to specify an array of rx_queue_id values alongside individual configurations for each queue. - Supporting a nb_rx_queues argument to define the number of queues to configure. When set to 0, the API applies a common configuration to all queues, similar to the existing rx_queue_id = -1 behavior. This enhancement allows for more granular control when configuring multiple Rx queues. Additionally, the API can act as a replacement for the older API, offering both flexibility and improved functionality.
