Re: [RFC PATCH v2 0/9] bql: Byte Queue Limits

BQL is dynamic, and will increase the queue limit more aggressively
than decrease it.  So for instance, we can track the largest queue
needed over 30 seconds which should be stable in the presence even in
the presence of fluctuating bandwidth.  The thing that worries me is
rather the HW queues conform to the queue characteristics described in
the patch.  If transmit completions are random and not regular, BQL
probably can't function well.

I think thats the challenge ;-> I wouldnt say it is random, but if my
understanding is correct the effect is a factor of number of stations
etc.

If you'd like to bring this up on some wireless devices that would be
great, I don't have easy access to any right now, but I can try to
help otherwise.

I am most curious as well...
