This is not acceptable - the internal header files (*_i.h) are not
supposed to be included outside the directory in which they are defined.

This is looking at an internal state in a way that makes it more
difficult to maintain the code in the future. A cleaner design is going
to be needed here, e.g., with a callback function. Wouldn't the way used
in AP code be suitable for this? See how hostapd_wpa_auth_set_eapol() is
used to handle WPA_EAPOL_authorized changes in src/ap/wpa_auth_glue.c
for an example. wpa_supplicant/ibss_rsn.c should be able to do the same.
