[ath9k-devel] hardware queue

[ferran <ranker72@gmail.com>]

Hi there,

I am monitoring the debugfs ath9k_htc/queue file to detect high use of
an AR9271 wifi dongle.  When I inject traffic through it, I see that
Best-Effort queue gets constantly filled and emptied, while the other
queues remain empty. My problem is that the value "Data BE endpoint"
keeps going down to zero, and it makes a false-negative for my watchdog.
I also could code a simple memory system, but before that I am trying to
get the best data source.

As a detail, I am polling debugfs every 100ms, but it doesn't look to
update that fast.

So, is there any way to get more accurate info on the occupancy of the
queues? If not, my aim is to detect a full-load of the dongle, so any
suggestions in this direction are more than welcome.

Regards,
Ferran
