IFICT this flag will not take the effect since we have SUPPORTS_PS.
Also for WAP3 (802.11w) we fallback to software encryption - 
that will prevent fast xmit as well. To truly enable
fast xmit, I think we would need add hardware encryption support for 
WPA3 and also compromise by remove Power Save support (which is disabled by
default, so that's possibly fine).
