Searching through the driver source code would probably be the best way
of figuring that out..

It would be from mac80211 in the case of ath5k (or well, any driver
using mac80211) _if_ they were to need this functionality. However, they
do not. IWPMKIDCAND event is only used when the driver takes care of
roaming (scanning, BSS selection, determination of when to roam), i.e.,
when wpa_supplicant is not processing scan results (ap_scan=2 mode). In
ap_scan=1 case (e.g., with mac80211), information about RSN
pre-authentication candidates is derived from the scan results and a
separate driver event is not needed.
