* Function: saveInterfaceEAPOLConfiguration
* Purpose:
* Save the SCNetworkInterface EAPOL information for System and LoginWindow
* modes.
*
* Iterate over the changed SCNetworkInterfaceRef list cfg->sc_changed_if,
* and for each interface, grab the EAPOL extended information from
* cfg->sc_prefs. Then set the corresponding value in the new
* freshly created SCPreferencesRef.
*
* All this done to avoid a writer getting Stale Object errors
* when it has its own SCPreferencesRef object that it manipulates while
* having an EAPOLClientConfigurationRef open.
