[PATCH 1/6] Use an enum for EAP SM requests
Dan Williams
dcbw
Mon Oct 24 09:00:19 PDT 2011
Control requests will be extended for non-EAP uses later,
so it makes sense to have them be generic. Furthermore,
having them defined as an enum is easier for processing
internally, and more generic for control interfaces that
may not use field names. The public ctrl_req_type/field_name
conversion function will be used later by the D-Bus
control interface too.
