Callback that should be used to process the next round. Usually set to the process function of an EAP submodule. |

Ingest an eap_packet into a thawed or newly allocated session.
If eap_packet is an Identity-Response then allocate a new eap_session and fill the identity.
If eap_packet is not an identity response, retrieve the pre-existing eap_session_t from request data.
If no User-Name attribute is present in the request, one will be created from the Identity-Response received when the eap_session was allocated.

Here is the call graph for this function: Here is the caller graph for this function:| void eap_session_freeze | ( | eap_session_t ** | eap_session | ) |
Freeze an eap_session_t so that it can continue later.
Sets the request and pointer to the eap_session to NULL. Primarily here to help track the lifecycle of an eap_session_t.
The actual freezing/thawing and management (ensuring it's available during multiple rounds of EAP) of the eap_session_t associated with REQUEST_DATA_EAP_SESSION, is done by the state API.

Retrieve an eap_session_t from the request data, and set relevant fields. Primarily here to help track the lifecycle of an eap_session_t.
