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: 97d37d2c1f6b ("net/mlx4: remove device register remap") Cc: stable@dpdk.org Signed-off-by: Yunjian Wang --- drivers/net/mlx4/mlx4.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/net/mlx4/mlx4.c b/drivers/net/mlx4/mlx4.c index 7cd35cd3ca..c72587b7ef 100644 --- a/drivers/net/mlx4/mlx4.c +++ b/drivers/net/mlx4/mlx4.c @@ -201,6 +201,8 @@ mlx4_proc_priv_init(struct rte_eth_dev *dev) struct mlx4_proc_priv *ppriv; size_t ppriv_size; + mlx4_proc_priv_uninit(dev); + /* * UAR register table follows the process private structure.
