From: Sam Leffler <sleffler@xxxxxxxxxxxx> Add NL80211_SCAN_FLAG_LOW_PRIORITY flag support. It tells drivers that this is a low priority scan request, so that they can take necessary action. Drivers need to advertise low priority scan capability during registration.
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.
