Why not keeping uint16_t?

> +	uint32_t tx_explicit:1; /**< Explicit TX flow rule mode. */
> +	uint32_t manual_bind:1; /**< Manually bind hairpin queues. */

Please describe more the expectations of these bits:
What is changed at ethdev or PMD level?
What the application is supposed to do?
Why choosing one mode or the other?
