	 * This function indicates the routing realms and NAI decoration

	 * to the adaptation module. The values are needed in the generation of 

	 * EAP (outer) Identity Response and need to be dynamically obtained from 

	 * the Wimax engine scanning results. The EAP stack requests these values

	 * from the default EAP type when it needs to respond to an EAP Identity

	 * Request. More info (e.g. the allowed character set) is available 

	 * in RFC 4242.

	 *

   * @param routing_info is a null pointer if RoutingRealm is not used. Otherwise it contains

	 * a string in the format "RoutingRealm1!RoutingRealm2!RoutingRealm3" (no null termination)

	 * in which RoutingRealm1 is the 1st location on the route, RoutingRealm2 is the 2nd 

	 * location and so on. The parameter does not contain the home realm, as the home realm 

	 * is static and requested from the adapatation module separately (obtained from the 

	 * provisioning data). From this info, the EAP stack generates a NAI such as

	 * "RoutingRealm2!RoutingRealm3!HomeRealm!{nai_decoration}username@RoutingRealm1".

	 *

	 * @param nai_decoration is null if NAI decoration is not used. Otherwise it contains

	 * a string in the format "{avp1|avp2|avp3}", which the EAP stack copies to NAI. The NAI 

	 * above becomes

	 * "RoutingRealm2!RoutingRealm3!HomeRealm!{avp1|avp2|avp3}username@RoutingRealm1".
