This I don't understand - what "comparison" are you talking about? > Also force IEEE80211_RATE_MANDATORY_A for 10 MHz and 5 MHz channels > as they use "half-clocked" respectively "quarter-clocked" operation > of the OFDM rates (IEEE Std 802.11-2016, 17.1.1). I don't think this is correct - the way the flags are used, anything on 2.4 GHz would never bother to check the MANDATORY_A flag. johannes
