net/mlx5: change device reference for secondary process
rte_eth_devices[] is not shared between primary and secondary process, but a static array to each process. The reverse pointer of device (priv->dev) is invalid. Instead, priv has the pointer to shared data of the device, struct rte_eth_dev_data *dev_data; Two macros are added, #define PORT_ID(priv) ((priv)->dev_data->port_id) #define ETH_DEV(priv) (&rte_eth_devices[PORT_ID(priv)]) Signed-off-by: Yongseok Koh <yskoh@mellanox.com>
