This seems ridiculous, if userspace sets the interface down it might get
a stale response, but you're writing dozens of lines of code just to
avoid _that_?

Maybe also to avoid querying the same STA twice but if the firmware
can't cope with it then it can still reject it (or the driver), is there
really a good reason to have all this complexity to prevent it?

Tracing on the output path, on the other hand, would be useful?
