I missed the previous versions of this patch series, but what 'necessary
action' is needed for a low priority scan request. Patch #6 gives a clue
so my assumption is that a low prio scan will be *aborted* when
associated and data traffic is available. Is that correct? Could it also
*suspend* the low prio scan? Just curious whether there is an explicit
behavioral requirement here. I probably should dig in previous versions
of this patch series. Too bad the cover letter of this one does not have
full change log.
