Exactly, and, no, thank you for making clear what is needed. :) A little more on this: I think struct netmap_slot is convenient due to the fact that in zero-copy one wouldn't want to mess with the actual buffer for speed and userland code already touches slot internals for each ring transition so there is no performance degradation. The key benefit is that if userland can use this storage freely netmap(4) doesn't get in the way of building complex setups that require decoupled logic and each ring "hop" may alter the state as required.
