EAP state machine

[Sarah Thomas]

Hi,

Would like to know, from where the EAP state machine is getting triggered
for a case like below:

 When  we are receiving a message from radius server , in
ieee802_1x_receive_auth, if we receive, RADIUS_CODE_ACCESS_CHALLENGE,
sm->eap_if->aaaEapReq  is set to TRUE, after which
ieee802_1x_decapsulate_radius is called .

After returning, from there eapol_auth_step(sm); is called which triggers
the EAPOL state machine.

After that, looks like EAP state machine is getting triggered to handle the
state of AAA_RESPONSE.
