Hi,

Since it's all hard to read in plain markdown, I've uploaded it to the
suggested fields:

https://www.radiotap.org/fields/U-SIG

https://www.radiotap.org/fields/EHT

The EHT one got pretty big, but OTOH since we have TLVs now we can make
it variable size, and don't need the split like we had with HE where we
did HE, HE-MU and HE-MU-other-user, which is nice.

Comments welcome. I'll probably (have to) continue to tweak it as our
implementation progresses, but all the bigger open questions I had are
resolved, and it looks like I can put everything our sniffer will report
into it.

The only thing I know of right now that I'm not entirely sure about is
the Content Channel Index thing - i.e. "which preamble of the
transmission did I capture". Our DSP appears to provide this in trigger-
based RU allocation format, and I have to check how to use that
properly.
