That note seems to be a bit unclear.

It's also starting to dawn on me that you actually wanted cases where
you only set the minimum time? Like in wireless extensions? You're also
only ever setting the minimum time defaults if none were given, this is
in cfg80211_trigger_scan().

So maybe you need to clarify the semantics? Clearly, I haven't
understood this yet from the documentation.

Otherwise it seems to me that there should be min/max always set, even
if mac80211 only ever uses min?
