Wondering if it is perhaps a driver issue. This configuration works with the HS20-enabled Intel driver and Samsung Galaxy IIS, I.e. I know my APs are sending and responding.

I'm not sure whether there is a list of drivers supporting offchannel
Action frame TX prior to association.. Your easiest option today is
likely to be anything using ath9k or ath9k_htc. Other drivers may work,
but those two are the ones I'm using for most of my testing (well, when
having to use real hardware instead of mac80211_hwsim).
