I will patch this next. Test to come tomorrow, though, Dave.
Update: I changed my mind; I will fight against Gravity in the arvo. See below.
WMM test parameters:
tx_queue_data2_aifs=3

Click me to download flent data and tcpdump capture.
Note that I didn't see any kernel warning; hence the driver is not calling netif_napi_add() with a weight value higher than the one defined (16).
if (weight > NAPI_POLL_WEIGHT)
netdev_err_once(dev, "%s() called with weight %d\n", __func__,
weight);
