+config NET
+	bool "Networking support"
+	default n
+	---help---
+		Enable or disable all network features
+
+if NET
+
+config NET_NOINTS
+	bool "Not interrupt driven"
+	default n
+	---help---
+		NET_NOINT indicates that uIP not called from the interrupt level. 
+		If NET_NOINTS is defined, critical sections will be managed with semaphores;
+		Otherwise, it assumed that uIP will be called from interrupt level handling
+		and critical sections will be managed by enabling and disabling interrupts.
+
+config NET_MULTIBUFFER
+	bool "Use multiple device-side I/O buffers"
+	default n
+	---help---
+		Traditionally, uIP has used a single buffer for all incoming and
+		outgoing traffic.  If this configuration is selected, then the
+		driver can manage multiple I/O buffers and can, for example,
+		be filling one input buffer while sending another output buffer.
+		Or, as another example, the driver may support queuing of concurrent
+		input/ouput and output transfers for better performance.
+
+config NET_IPv6
+	bool "IPv6"
+	default n
+	---help---
+		Build in support for IPv6.  Not fully implemented.

+
+config NET_TCPURGDATA
+	bool "Urgent data"
+	default n
+	---help---
+		Determines if support for TCP urgent data notification should be
+		compiled in. Urgent data (out-of-band data) is a rarely used TCP feature
+		that is very seldom would be required.

+		Number of TCP/IP read-ahead buffers (may be zero)
+
+config NET_TCPBACKLOG
+	bool "TCP/IP backlog support"
+	default n
+	---help---
+		Incoming connections pend in a backlog until accept() is called.
+		The size of the backlog is selected when listen() is called.

+config NET_UDP
+	bool "UDP Networking"
+	default n

+	---help---
+		Enable or disable UDP networking support.

+	bool "UDP checksums"
+	default n
+	---help---
+		Enable/disable UDP checksum support
+

+		The maximum amount of open concurrent UDP sockets
+
+config NET_BROADCAST

+	---help---
+		Enable IGMPv2 client support.

+config PREALLOC_IGMPGROUPS
+	int "Number of pre-allocated IGMP groups"
+	default 4
+	---help---
+		Pre-allocated IGMP groups are used only if needed from interrupt
+		level group created (by the IGMP server). Default: 4.

+		Enables building of the SLIP driver. SLIP requires
+		at least one IP protocol selected and the following additional
+		network settings: NET_NOINTS and NET_MULTIBUFFER.
+
+		NET_BUFSIZE *must* be set to 296.  Other optional configuration
+		settings that affect the SLIP driver: NET_STATISTICS. 
+		Default: Ethernet
+
+		SLIP supports point-to-point IP communications over a serial port.
+		The default data link layer for uIP is Ethernet. If NET_SLIP is
+		defined in the NuttX configuration file, then SLIP will be supported.
+		The basic differences between the SLIP and Ethernet configurations is
+		that when SLIP is selected: 
+		
+		* The link level header (that comes before the IP header) is omitted. 
+		* All MAC address processing is suppressed. 
+		* ARP is disabled.
+		
+		If NET_SLIP is not selected, then Ethernet will be used (there is
+		no need to define anything special in the configuration file to use
+		Ethernet -- it is the default).
