Linux 4.10's ath9k Driver Should Have Lower Latency & Less Bufferbloat

How to benchmark this?

Check for the bufferbloat rating. Everything else than an A is shit, which is easy for LEDE/OpenWRT. It's mostly depending upon your router.

ath9k
* add device tree bindings
* switch to use mac80211 intermediate software queues to reduce latency and fix bufferbloat

Do any of these require hostapd configuration changes?

pfSense 2.3.2 (5Ghz "N"). Atheros AR9485. Transparent squid proxy in the mix too, no clue how it may have affected things.

Has anyone tried Google's amazing congestion control algorithm, BBR, introduced in Linux 4.9 to resolve bufferbloat issue?

LWN says these bits of code "allow network protocols (usually TCP) to maximize the throughput of any given connection while simultaneously sharing the available bandwidth equitably with other users."

Here are few benchmarks:

however, the result covers only bbr/fq_codel, not bbr/fq.
