TCP/IP Stack Configuration Parameters			RETAIN/CHANGE	Remark
Use TCP/IP Stack			CHANGE	Check the checkbox to use the TCP/IP Stack
	IPv4		RETAIN	Enabled by Default.
	IPv6		RETAIN	Disabled by Default. You do not require IPv6 for this demo.
Use TCP				Enabled by default. TCP is a standard transport layer protocol described in RFC 793. It provides reliable stream-based connections over unreliable networks, and forms the foundation for HTTP, SMTP, and many other protocol standards.
	Max TX Segment SIze		RETAIN	TCP Maximum Segment Size for TX. This parameter sets a hard limit so that the TX buffers do not overflow
	Max Local RX Segment Size		RETAIN	TCP Maximum Segment Size for RX (MSS). This value is advertised during TCP connection establishment and the remote node should obey it.
	Max Non-Local RX Segment Size		RETAIN	Maximum Segment Size for RX (MSS) for non local destination networks.
	Default TX Size		RETAIN	Default socket TX buffer size. Note that this setting affects all TCP sockets that are created and, together with TCPIP_TCP_MAX_SOCKETS, has a great impact on the heap size that's used by the stack
	Default RX Size			Default socket RX buffer size. Note that this setting affects all TCP sockets that are created and, together with TCPIP_TCP_MAX_SOCKETS, has a great impact on the heap size that's used by the stack
	Enable TCP Sockets Dynamic Options		RETAIN	Enable the TCP sockets dynamic set/get functionality
	Start Time-out -ms		RETAIN	Timeout to retransmit un-acked data, ms
	Delayed Ack Time-out -ms		RETAIN	Timeout for delayed-acknowledgment algorithm, ms
	Fin Wait 2 Time-out -ms		RETAIN	Timeout for FIN WAIT 2 state, ms. Automatically reset the socket on your end if the other side fails to close its connection
	Keep Alive Time-out -ms		RETAIN	Timeout for keep-alive messages when no traffic is sent, ms. When two hosts are connected over a network via TCP/IP, TCP Keepalive Packets can be used to determine if the connection is still valid and terminate it if needed.
	Close Wait Time-out -ms		RETAIN	Timeout for the CLOSE_WAIT state, ms. If the application doesn't call TCPIP_TCP_Disconnect() as needed and expects the stack to automatically close sockets when the remote node sends a FIN, a timer is started so that the socket will eventually be closed automatically

	Max Sockets		RETAIN	Maximum number of UDP sockets that can be opened simultaneously. These sockets will be created when the module is initialized.
	Default TX Buffer Size		RETAIN	Default socket TX buffer size. Note that this setting affects all UDP sockets that are created and, together with TCPIP_UDP_MAX_SOCKETS, has a great impact on the heap size that's used by the stack
	Calculate TX Checksum		RETAIN	Enabled by Default. Calculate and transmit a checksum when sending data. Checksum is not mandatory for UDP packets but is highly recommended. This will affect the UDP TX performance.
	Calculate RX Checksum		RETAIN	Enabled by Default. Check incoming packets to have proper checksum.
	TX Queue Limit		RETAIN	The maximum number of TX packets that can be queued by an UDP socket at a certain time
	RX Queue Limit		RETAIN	The maximum number of RX packets that can be queued by an UDP socket at a certain time. Once this limit is reached further incoming packets are silently discarded
