repeating the tests in my prior post after this commit.
There seems to be an improvement; however, I still results like this below running simultaneous netperf from two clients on same 5 GHz band.

Irtt results run simultaneous with the two netperf sessions looks ok...

Multiple client netperf/irtt on 2.4 GHz band have similar features but less pronounced.
May this helped?
The unit of the return value of ieee80211_get_rate_duration is nanoseconds, not milliseconds.
Regardless, I appreciate the effort.
