Hmm, if this [1] is the official standard, then no, it is not defined. Don't
know when this was added in wireshark, and it was only added implicitly in
the code (no header files etc). But since it was there, I figured it would
be a good idea to re-use it (unaware that there was some "standard").

How shall we proceed, propose that on some radiotap mailing list officially?

Yeah, it's a little easier for the driver, and I thought it would be
cleaner to get this reported through a flag.
