Why does the driver need to provide the radio, it already provides the
frequency?

But then I wonder if this doesn't go a step too far? This is pretty much
pretending that monitor only exists on a specific sub-radio, but ...
what for? Even userspace could filter on the frequency.

I mean ... I get that you're trying to preserve a notion that you had
that an interface exists on a given PHY and they're all separate, but
they're not really separate any more, get used to it?
