Hi,
I know this is a LONG time ago, but nonetheless...

I don't, at least today, but I don't see relevant changes since then,
understand why this was two combinations, one with fewer interfaces.
It seems that radar detection is mostly independent of the interface
types, at least as far as the code is concerned.
Are there some other considerations, that prevent declaring
radar_detect_widths together with the regular hwsim_if_limits? It
obviously cannot actually be *used* for all?
