Drivers can offload EAPOL 4WHS to wpa_supplicant during roaming with non-FT AKMs. In that case supplicant needs to know rejected links info to validate AP's MLO Link KDEs in 3/4 frame. Ex: Driver handles only re-association request and response frames while doing roaming with non-FT AKM then offload 4WHS to wpa_supplicant > > In any case, I have no driver I deal with that would ever use this API, > so I can't really do anything about it. No problem, I will post the required changes for cfg80211_roamed/NL80211_CMD_ROAM path, hope that is fine. > > johannes
