---------------------------------------------------
03f,13jan06,djp   removed rwos dependencies
03e,09jan06,djp   Added required includes
03d,28nov05,djp   replace WRN_INET with WRSEC_INET
03c,08may03,sam(teamf1) added macros GET_PROTOCOL,IS_IP_MINE,NEITHER_OF.
03b,24Apr03,sam(teamf1) renamed ipsec_get_pmtu_message to ipsecPmtuMessageGet. 
03a,15apr03,sam (teamf1)added function to get PMTU age(SPR #86677).
02b,25mar02,rpt   added DF bit configuration to the network interface class to
                  enable PMTU per interface. 
02a,21mar02,rpt   Changed struct IPSEC_NETWORK_INTERFACE declaration and func
                  declarations to use WRN_INET_ADDR* instead of ULONG.
01a,19mar02,rpt   Extracted from WindNet IPSec 1.1, added modification history
