Sure, no objection to that. However, just arbitrarily adding a "change
channel" call, without thinking about the realities of the code already
supporting multi-channel concurrency, remain-on-channel and hw-scan
operations won't get us very far and just lead to issues with the API.

Sure. I'd just like to ask that the API is actually useful in more than
the default single-channel support BSS-only case :)
