IEEE 802.11w support in wpa_supplicant ("Management frame protection required, but client did not enable it" error)

I have enabled IEEE 802.11w (management frame protection mode) in my AP
- running hostapd - with "ieee80211w=2" (required/mandatory), but when I
try to connect using wpa_supplicant I get the following error message:
"Management frame protection required, but client did not enable it".
I searched the man pages as well as any documentation of the supplicant
I could find and the only mention of this is that in order to activate
it I have to compile the supplicant with "CONFIG_IEEE80211W=y". I did
that (I also used "CONFIG_EAP_GPSK_SHA256=y" as well) and restarted the
supplicant, but I still get this error.
I tried to specify "ieee80211w=2" in the supplicant configuration file
as well (a wild guess, I know) and the strange thing is that before I
recompiled my supplicant with "CONFIG_IEEE80211W=y" (this option wasn't
active before) it used to complain that the option I used - ieee80211w -
is "not recognised".
After recompilation when "CONFIG_IEEE80211W=y" was included in my
.config file, the supplicant isn't complaining any more, but IEEE
802.11w doesn't seem to be activated/working either (besides, I am not
even sure specifying "ieee80211w=2" in my wpa_supplicant.conf is the
right thing to do as this "option" is not documented anywhere) - I get
exactly the same message on the AP side - "Management frame protection
required, but client did not enable it", while on the supplicant side I
get a timed-out message.
Is IEEE 802.11w supported in the supplicant and how do I activate it/use
it? What am I missing?
