Can we add an API such as rte_eth_get_device(pord_id)
for example: struct rte_eth_dev * rte_eth_get_device(uint16_t port_id) { return &rte_eth_devices[port_id]; }
An application is not supposed to access the struct rte_eth_dev. Which info do you need from this struct?
Applications cannot directly access the global variable rte_eth_devices[]. To obtain information about rte_eth_dev, they need to access the global variable through APIs instead of directly.
That's not the question. Which device info do you need, which is not already provided by one of the function rte_eth_*info* ? rte_eth_dev_get_dcb_info rte_eth_dev_get_reg_info rte_eth_dev_info_get rte_eth_rx_queue_info_get rte_eth_tx_queue_info_get rte_eth_dev_get_module_info
