Sign of the driver never reporting association.

No, that is of no importance to wpa_supplicant. This issue is not at the
supplicant level, but at the driver/SoftMAC. wpa_supplicant is just
waiting for the driver to report association here and that does not seem
to happen.

SoftMAC seems to be able to complete authentication (that is the
"authenticated" event above), but for some reason, it does not seem to
even try to associate after this. I would recommend directing this
question to SoftMAC maintainers.
