From: Sunil Kumar Kori <sk...@marvell.com>
hot_plug application does not perform any port setup
configuration via rte_eth_dev_configure() API. All the probed
Ethernet ports do not contain any Rx and Tx queues.
While detaching a device via rte_eal_hotplug_remove(), CNXK
driver expects Rx and Tx queues structures populated during
reset of PFC. So application gets crashed as data->rx_queues
and data->tx_queues are NULL.
Fixes: 9544713564f5 ("net/cnxk: support priority flow control")
