Is that necessary? Reads like we have 2 bytes free there?

And we only need 13 bits for the frequency (up to 8192 MHz, 60 GHz isn't
supported), so we could take out a few fractional ones for the S1G part?

Dunno, I mean, we probably also don't need the A-MPDU reference, even
radiotap doesn't make much representation on this, but it sort of
implies that it should be unique in a capture file, for which 16 bits
wouldn't be enough? (should probably clarify that though and say that
you should look only "close by" or something?)
