pmksa_cache_auth_add - Add a PMKSA cache entry : Pointer to PMKSA cache data from pmksa_cache_auth_init() : The new pairwise master key : PMK length in bytes, usually PMK_LEN (32) : Authenticator address : Supplicant address : Session timeout : Pointer to EAPOL state machine data : WPA_KEY_MGMT_* used in key derivation Returns: Pointer to the added PMKSA cache entry or NULL on error
This function create a PMKSA entry for a new PMK and adds it to the PMKSA cache. If an old entry is already in the cache for the same Supplicant, this entry will be replaced with the new entry. PMKID will be calculated based on the PMK.
