Thanks for the comments, all the comments are addressed in next version except

The num_tx_q here is different from data->nb_tx_queues.
The idpf PMD requires fixed txqs and rxqs when the idpf PMD requires creating a
vport.
The num_tx_q and the num_rxq_q are the values returned by backend.
But there'll be only data->nb_tx_queues txqs configured during dev_start.
