The point of telling you that it's a linux system is to say that there isn't
anyu "OpenWRT where the code would process".  It's the Linux kernel.

tc would let you introduce new qdisc's and you could perhaps create some
counters, but it will likely be before the hardware TX queue.
(if BQL / fq_codel are doing their thing, the hardware TX queue will be very
short... but maybe that's what you are trying to determine)

I suggest that you probably need to get into the ath9k driver, and add some
counters, or perhaps you'll find counters that are already there.
