I think deprecation notice not required for above ones. But you KNI patchset updates rte_kni_conf and rte_kni_ops. These are part of KNI API and changing them cause ABI breakage, but if new fields appended in these structs, this will not cause an ABI breakage, and I think that is better to do instead of deprecation notice, what do you think? And apart from above ABI issues, adding new fields to "rte_kni_ops" means DPDK application that use KNI should implement them, right? So this suggest everyone require to set promiscuity of KNI device should implement this. Can't we find another way that all can benefit from a common implementation?
