[Bloat] Steam In Home Streaming on ath9k wifi

[Caleb Cushing]

In home streaming is basically a high bandwidth low latency way of
streaming a game so you can play it on another machine. I'm not sure if
this is the best list to talk about this on, but since it involves wifi,
fq-codel, and cake, this seems like the best place maybe, I did start by
talking about this on the forums, but I think I've basically reached the
end of what documented configuration can do on the current LEDE, and
perhaps what can be done currently period. That said maybe I can offer up
this use case and help things improve in the future.

I've actually managed to get game streaming mostly smooth, but there's
still an occasional stutter (latency increase from ~5ms to around 100ms,
then it goes away again) that I haven't figured out. happy to provide more
information if it'll help this use case. note, the additional options
mentioned in the forum on src/desthost seem to actually make things worse.
