Ugh. Nobody will dissect that properly. Do you actually need this
information in userland _now_? Otherwise, Dave Young is moving the list
elsewhere and then we can properly define this in radiotap rather than
going with some other set. 0x80 in flags (not rate) is used to indicate
short-GI in wireshark, and it's all very confusing... I'd rather see a
new "HT rate" field added to radiotap.

Right. Who cares about IBSS :)
