I'm attaching a bunch of tests I've done using flent. They are all
"burst" tests with burst-ports=1 and burst-length=2. The testing
topology is:

                   AP ----> STA
                   AP )) (( STA
 [veth]--[br]--[wlan] )) (( [wlan]

You can notice that in some tests plot data gets cut-off. There are 2
problems I've identified:
 - excess drops (not a problem with the patchset and can be seen when
there's no codel-in-mac or scheduling isn't used)
 - UDP_RR hangs (apparently QCA99X0 I have hangs for a few hundred ms
sometimes at times and doesn't Rx frames causing UDP_RR to stop
mid-way; confirmed with logs and sniffer; I haven't figured out *why*
exactly, could be some hw/fw quirk)

Let me know if you have questions or comments regarding my testing/results.
