Wasn't my question. Do you observe any of your games using any codepoints?

Well, I was leaning towards cs4. I no longer remember what ef maps
into on linux wifi, particularly since qos_map_set was created for
hostapd. Is openwrt tweaking that at all?

These days my aps do not use 802.11e at all and I'm about to push a
change forcing a max of 2ms per AC via the beacon.

Clients on campus don't seem to use much dscp but I'm certainly seeing
ecn from apple devices now.
