[dpdk-dev] [PATCH v2 2/2] net/mlx5: fix mem leak when a device configured repeatedly

[wangyunjian]

From: Yunjian Wang <wangyunj...@huawei.com>

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

Fixes: 120dc4a7dcd3 ("net/mlx5: remove device register remap")
