The above is simplified, and the original is:
rte_eth_bond_slave_remove
-->__eth_bond_slave_remove_lock_free
---->slave_remove
------> rte_eth_dev_internal_reset
--------> rte_eth_dev_rx_queue_config
----------> eth_dev_rx_queue_config
------------>i40e_dev_rx_queue_release
rte_eth_dev_close
-->i40e_dev_close
---->i40e_dev_free_queues
------>i40e_dev_rx_queue_release(not been called due to nb_rx_queues and nb_tx_queues are 0)
