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.
