My conservative proposal was to put a notice anyway. > > Nonetheless, what I would like to get from Thomas and Panu is a path forward for this now: > a) If we agree to consider this an ABI change, please merge the notice for 16.7; Panu was noticing 3 things (and I agree with them): - it is an API change - they can be grouped in only one list item - it is better to wait having more changes to break an API About the third point, in this specific case, I think it is acceptable because: - it should not break the ABI - the impact of the API change is really small - I'm not sure the packet framework should be considered as a DPDK API. > b) If we agree this is too small for an ABI change, please let us agree now > to accept our quick patch for 16.11 for this change.
