AP mode with SAE/WPA3

[Heiko Thiery]

Hi,

I try to setup an AP using network-manager (NM) as frontend. When
configuring the NM connection with "wifi-sec.key-mgmt wpa-psk" the AP
is setup as expected. But when changing this value to
"wifi-sec.key-mgmt sae" I see the following errors in the
wpa_supplicant journal (using systemd):

I'm using NM 1.40.6 and wpa_supplicant v2.10.

I currently have no idea where to look for the problem. If it is a NM,
wpa_supplicant or kernel/driver problem. Can someone give me a hint or
know where the problem comes from?

Thanks
