We will need a key management type (key_mgmt), an EAP method (eap), an EAP identity string (identity), an EAP password string (passwd), an 802.11u realm (realm), an 802.11u domain (domain), and an 802.11u HESSID (hessid)
Example: key_mgmt="WPA-EAP"
eap="TTLS"
identity="testuser"
passwd="testpasswd"
realm="localhost.localdomain"
domain="localhost.localdomain"
hessid="00:00:00:00:00:01"
We can then use these variables to call the set_wifi_extra() method
Example: vap_profile.set_wifi_extra(key_mgmt, eap, identity, passwd, realm, domain, hessid)
