I don't know.

For the record, the encoding is to use a separate radiotap namespace for
each antenna, and then put an antenna signal and antenna field into it,
with the signal value and antenna number, respectively.

It's honestly not the greatest encoding, but it's sometimes useful to
have that data.

I've been hoping to replace namespaces with TLVs, but obviously in this
case that doesn't work since the namespace holds the two pieces of
information together ...
