No particular comments on the code yet but latency issues has got me
thinking about the filtered frames stuff and if we really need it. How
much benefit does keeping these frames give us instead of just
dropping them?
If the station goes to sleep, it'll incur latency by design. The
filtered frames stuff is really just a way to close the race between
giving a packet to the device and the station going to sleep -- as such
I think we should really keep it.
