Thanks, applied. This does not fix the exact behavior since the client
is allowed to complete association, but this is clearly improving the
previous implementation. wpa_drv_set_countermeasures() like
functionality and changes in the drivers would be needed to make the
IEEE 802.11 authentication and association fail when countermeasures are
in effect.
