No, setting it to 0 in either case results in default behavior.

I'm unable to change the QoS null behavior at all (but I can
change the timeout as mentioned previously).  I noticed that
field is commented out in the wcnss ini file, perhaps FW
doesn't support modifying it after all?

Did you guys experiment with the approach of making delete sta
indication remove the sta in mac80211?  I see that it calls
ieee80211_report_low_ack(), but as I understand it, that just
notifies userspace without taking any action on its own.
Perhaps in mesh user mpm case it should delete the sta.

(If we did that, we'd have to re-peer and then mac80211 would
re-add the sta, but compared to the overhead of sending
20 failed QoS nulls times the number of peers every 3 seconds,
it's probably lower.)
