Well, that's not a bad point, but at least it's not created via magic
ioctls etc.

Actually, I first thought that as well, but in fact the userspace MLME
in wpa_supplicant doesn't even need to connect these events, it simply
checks which auth sequence number it sent and then assumes that whatever
it did was correct and adds the sta to the associated/auth list on the
callback.
