My understanding is that:

  • Make WiFi fast project is what you are talking about. It mentions the USENIX paper.
  • Linux mac80211 wifi stack, used by ath9k, ath10k, ath11k, ath12k?, mt76, brcmsmac, rt2x00, rtl8xxxu, rtw88, rtw89 and possibly others was reworked to support:
    • per station TX queues that are automatically managed using fq_codel - to keep
      the latency below target
    • aql - not sure what this is exactly used for
    • airtime fairness - to maximize the performance by not letting stations with low rates use more than their fair share
