I'm confused now, this all looks fine from a driver perspective.

We send SAE commit, receive SAE commit, send SAE confirm, never receive
a response. There's no response in sniffer nor tracing data, so that
matches up. There are a couple of retries of the confirm response, but
that seems OK.

Seems like maybe iwd builds an SAE confirm that the AP doesn't like, try
wpa_supplicant I guess.
