[1/3] eventdev/eth_rx: add API to burst add queues to Rx adapter
Checks
Commit Message
This patch introduces a new API, rte_event_eth_rx_adapter_queues_add(),
to allow bulk addition of multiple Rx queues in the eventdev Rx adapter.
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.
A new internal PMD operation, eventdev_eth_rx_adapter_queues_add_t, has
been introduced to enable this functionality. It takes an array of
receive queue IDs along with their corresponding queue configurations.

Since we are only verifying the queue_conf parameter here, and the same
configuration can be used for all queues when nb_rx_queues = 0, I will mention
the index of the queue_conf that contains an invalid configuration.
