Actually, I should say though - the question was more whether we even need/want that, rather than whether we can do it later or not. If we should protect this data/information then IMHO we should do it now, but it's not clear to me that we should, given that we also don't have encrypted association response and we still take information from there too, etc. johannes -- ath11k mailing list ath11k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath11k
