This patch series implements Airtime-based Queue Limit (AQL) in the mac80211 and Ath10k driver. It is based on an earlier version from the ChromiumOS tree[0].

This version has been tested with QCA9884 platform with 4.14 kernel. Tests show AQL is able to reduce latency by an order of magnitude in a congested environment without negative impact on the throughput.
