+ * There are two strict backwards compatibility modes:
+ *      TCPV40HDRS - BSD 4.3 based stack. TCP/IP versions prior to 4.1.
+ *      TCPV41HDRS - BSD 4.4 based stack. TCP/IP versions 4.1 and higher.
+ *
+ * __USE_LIBC_TCPIP will add additional features for better compatability
+ * with the current BSD stack. It can be defined together with the two
+ * strict modes, but will have little effect in TCPV40HDRS mode.
+ *
+ * The default mode non-strict with __USE_LIBC_TCPIP defined.
