In my opinion, this is in fact something the AR6k shouldn't do - at
least not on Linux.

We have a perfectly good (and *much* more versatile) traffic control
architecture in the kernel. Having flow-controlled priority queues
in the AR6k as well thus adds little value and - if it was actually
used - would in fact interfere with the kernel traffic control.
