- Yep, that would be the idea.
This way applications can reuse these structures "as is" or change some
values before calling rx / tx _queue_setup.


- By the way, I noticed that rte_eth_dev_info_get() is only resetting part
of the dev_info structure given by the user.
We might want to reset the dev_info structure to 0 before filling it ?
