I'm afraid this wording will be confusing, because every drivers
free their buffers :)
What about "Free Tx mbuf on demand" ?

And please, move this line upper, just after "Rx interrupt".

We also need to carefully review the doc you provided (thanks).
First quick comment, please wrap lines shorter in the doc.

About the function prototype, I've seen a double space :)
I think you could use rte_errno (while keeping negative return codes).
