ath10k: poor latency performance

Description

ath10k both qca988x & qca99xx have poor latency when used at high speed, saturating the wifi link, or when qos is used. constant spiking, uneven latency.

example: dir-862L as host ap, internet line is 30mbps/5mbps (actual available is 35mbps/5.4mbps), use htb or hfsc doesnt matter. r7800 is using client mode to the dir-862L over 5ghz. link rates are around 780M/526M using ch 149, snr is always over 32 at all times.

when qos downlink limit is reached there is latency spikes. but if i connect to the dir-862L over 2.4ghz which is the ath9k interface, latency is smooth, stable, even.

why cant ath10k provide a stable latency especially when qos is used? ath10k has airtime fairness as well, & fq_codel in mac80211 has already been showed working with ath10k.
