I investigated a little further and the problem is probably that
I'm running a minimal Linux kernel which was compiled without
CONFIG_CFG80211_WEXT :-).

Anyways, thanks for applying the patch!

Makes sense, applied.

This less so, we even have a few test cases we run regularly, but I
don't know. Maybe there's something special in those configuration
files that we don't test for otherwise.

[PATCH] mac80211_hwsim: suggest nl80211 instead of wext driver in documentation

[Linus Lüssing]

For mac80211_hwsim interfaces, suggest to use wpa_supplicant with the more
modern, netlink based driver instead of wext.

Signed-off-by: Linus Lüssing

Actually, I wasn't even able to make a connection with the configuration
files and information provided in
Documentation/networking/mac80211_hwsim/{README,hostapd.conf/wpa_supplicant.conf}

Changing -Dwext to -Dnl80211 helped and made the WPA-PSK connection with
mac80211_hwsim interfaces work for me.
