//  Module: EPTF_CLL_Transport_IPsecHandler_Definitions
// 
//  Purpose:
//    This module contains type definitions that used by EPTF_CLL_Transport_IPsecHandler.
//
//    The Transport_IPsecHandler module provides IP sec functionality for EPTF_Transport.
//    Only IPL4 is supported. It uses the XFRM API of the TCCUseful Functions.
// 
//  Module Parameters:
//    -
//
//  Module depends on:
//    <TCCIPsec_XFRM_Definitions>
//    <EPTF_CLL_Base_Definitions>
//    <EPTF_CLL_HashMap_Definitions>
//
//  Current Owner:
//    Jozsef Gyurusi (ETHJGI)
// 
//  Detailed Comments:
//    To create IP sec connection from A->B (A and B should be on different machines):
//      - add SP by calling the function <f_EPTF_Transport_IPsecHandler_createSP> with the A and B addresses on both hosts
//      - add SA with <f_EPTF_Transport_IPsecHandler_createSA> with the A and B addresses on both hosts
//      - open listen port with Transport: <EPTF_CLL_Transport_Functions.f_EPTF_Transport_listen> at addr B
//      - connect to the listen port with Transport: <EPTF_CLL_Transport_Functions.f_EPTF_Transport_connect> from A to B
//      - send messages with <EPTF_CLL_Transport_Functions.f_EPTF_Transport_send> from A to B
//      - close connection at A and B with <EPTF_CLL_Transport_Functions.f_EPTF_Transport_close>
//      - remove SP on A and B: <f_EPTF_Transport_IPsecHandler_deleteSP>
//      - remove SA on A and B: <f_EPTF_Transport_IPsecHandler_deleteSA>
//
//    The messages from A and B will be encrypted while the SA and SP exists. If SA and SP is deleted before connection is closed
//    The connection close messages will not be encrypted.
//
//    If the TCP connection closes the EPTF_TransportIPL4 automatically deletes the SA and SP if exists for the TCP connection
//    when the connClosed event is handled

//  Purpose:
//    The component that implements the IPSec handling feature in EPTF Transport
// 
//  Elements:
//    c_EPTF_Transport_IPsecHandler_saHashMapName - *charstring* - hashmap name used for SA handling

//    v_SAAddInfo_List - <SAAddInfo_List> - the database for SA handling
//    v_Transport_IPsecHandler_saFBQId - <EPTF_FreeBusyQueue> - FreeBusyQueue for SA handling
//
//    c_EPTF_Transport_IPsecHandler_spHashMapName - *charstring* - hashmap name used for SP handling
//    v_EPTF_Transport_IPsecHandler_spHashMapId - *integer* - hashmap id used for SP handling
//    v_SPAddInfo_List - <SPAddInfo_List> - the database for SP handling
//    v_Transport_IPsecHandler_spFBQId - <EPTF_FreeBusyQueue> - FreeBusyQueue for SP handling
//
//    v_EPTF_Transport_IPsecHandler_initialized - *boolean* - prevents multiple init by calling <f_EPTF_Transport_IPsecHandler_init_CT> several times
//
//  Detailed Comments:
//   The <EPTF_TransportIPL4_CT> component extends this component
