[dpdk-dev] [PATCH v1] net/i40e: fix RX/TX setup when restart port

[Zhirun Yan]

Before this patch, there are two functions that will clear RX/TX queues
number: rte_eth_dev_close() and i40e_dev_free_queues(). But if also
i40e_dev_free_queues() clear it, RX/TX queues will not set up correctly
when restart port.

Fixes: 6b4537128394 ("i40e: free queue memory when closing")
