That's not wrong, that's just NLA_F_NESTED | NL80211_ATTR_MBSSID_CONFIG, since it *is* in fact a nested attribute. > Switching to nla_nest_start_noflag() which ommits the NLA_F_NESTED > flag (like most other similar functions do) fixes this: > > GetWiphy: Type: 1 > GetWiphy: Type: 2 > GetWiphy: Type: 46 > GetWiphy: Type: 306 <-- correct enum value > GetWiphy: Type: 316 Let's say it _changes_ it, but it doesn't _fix_ it, since it's not broken. Using nla_nest_start_noflag() is a legacy thing, it shouldn't be done any more. You need to update your userspace, I'm not applying this patch. johannes
