Thanks for your comments, I will ask maintainer to help fix this problem.

The following action should be executed for all non-primary processes.

If pmd doesn't implement "rte_eth_rx/tx_queue_info_get()" to query queue state, should use the default value instead of modifying the state, because it may be modified elsewhere.
