Ok, I did another capture.

1. iwd only knows credentials for a single SSID: kepler_test
2. kepler_test is the only SSID broadcasting on 6GHz channel 37 (or any
6GHz channel)
3. I captured 802.11 frames using a second device
4. I did a trace on the client in question
5. I captured dmesg and iwd logs
6. All captures were done simultaneously

All attached to capture2.tar. Contents:
capture2/dmesg2.txt      : dmesg
capture2/iwd_log2.txt    : iwd log using IWD_SAE_DEBUG=1
capture2/trace2.dat      : trace-cmd (iwlwifi, mac80211, cfg80211, iwlwifi_msg)
capture2/iwd_main.conf   : iwd config (/etc/iwd/main.conf)
capture2/kepler_test.psk : ssid config for iwd (/var/lib/kepler_test.psk)
capture2/capture2.pcapng : the external 802.11 frame capture


I disabled 5Ghz via BandModifier5GHz=0.0 (couldn't disable 2.4GHz as iwd
then complains about not being able to disable both)


One note about the client: It's running an Intel N100, so it's probably
on the lower end of devices that will be running a modern wifi 6e card.
So this increases the chances that the AP will send it's confirm before
the client will.


Best Regards
Jan
