It is likely the shortest length one would receive from hardware/firmware in normal mode, but it is not the shortest length for a valid IEEE 802.11 control frame. Both CTS and ACK frames have only 10 octets in the header (just one address). Having IEEE80211_HDR_MIN_LEN_CTRL defined to 16 would be a bit confusing.. CTS and ACK frames are received at least in monitor mode, so these frames with 10 octet headers will need to be processed in some cases. -- Jouni Malinen PGP id EFC895FA - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
