You mean HW that support UAPSD in STA mode:
a) "in some" way send trigger frames when goes to PS and expect EAP frame
b) should't go to PS during EAP exchange

Do you know how MVM handle this?

I am asking because mac80211 STA request VO by default (if UAPSD
supported by HW and AP report UAPSD supported) and now we decided to
send EAP also as a VO traffic from AP.
