Before, we did calculation for each mpdu even that wasn't required. In case of heavy traffic we will have eg. 15 mpdus in one ppdu. In case of attention flags we did 4 times __cpu_to_le32() for each rx`ed packet - while one calculation will be enough. For me this seems like resources (CPU) usage improvement. After some refactoring tries I decided to introduce this ieee80211_rx_status template. Seems this is easiest option here. This will be also similar code as we have already for fragmented RX packets.
