Please double check the condition "rx_queues" freed:
before the patch:
==========
if (eth_dev->data) {
internals = eth_dev->data->dev_private;
if (internals->action == DEV_CREATE) {
/*
* it is only necessary to delete the rings in rx_queues because
* they are the same used in tx_queues
*/
for (i = 0; i < eth_dev->data->nb_rx_queues; i++) {
r = eth_dev->data->rx_queues[i];
rte_ring_free(r->rng);
}
}
rte_free(eth_dev->data->rx_queues);
rte_free(eth_dev->data->tx_queues);
rte_free(eth_dev->data->dev_private);
}
==========
After the patch:
==========
internals = eth_dev->data->dev_private;
if (internals->action == DEV_CREATE) {
/*
* it is only necessary to delete the rings in rx_queues because
* they are the same used in tx_queues
*/
for (i = 0; i < eth_dev->data->nb_rx_queues; i++) {
r = eth_dev->data->rx_queues[i];
rte_ring_free(r->rng);
}
rte_free(eth_dev->data->rx_queues);
rte_free(eth_dev->data->tx_queues);
rte_free(eth_dev->data->dev_private);
}
==========
Thanks,
