When I use uart_driver_install with two uart like:
uart_driver_install(UART_NUM_0, BUF_SIZE * 2, BUF_SIZE * 2, 20, &uart_queue, 0);
uart_driver_install(UART_NUM_1, BUF_SIZE * 2, BUF_SIZE * 2, 20, &uart_queue, 0);

can I get uart_num in uart_queue?

The API is not intended to share a queue, sorry. Better to use two queues.
