[dpdk-dev] [PATCH 2/2] net/mlx5: fix mem leak when a device configured repeatedly

From: Yunjian Wang <redacted>

Currently, configuring a mlx device, it will allocate its
own process private in mlx5_proc_priv_init() and only frees
it when closing the device. This will lead to a memory leak,
when a device is configured repeatedly.

For example:
for(...)
do
	rte_eth_dev_configure
	rte_eth_rx_queue_setup
	rte_eth_tx_queue_setup
	rte_eth_dev_start
	rte_eth_dev_stop
done
