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.
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.

Changes from v1:
- Fix checkpatch error.
- Keep iterate the list of active_txq until an eligible txq's deficit become non-negative in ieee80211_next_txq(), instead of break the loop after one iteration.
- Enforce the AQL limit in ath10k's pulling mode in ath10k_htt_rx_tx_fetch_ind()
