Where does this value 16 come from? 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.
