+uIP is a very small implementation of the TCP/IP stack that is written
+by Adam Dunkels <adam@sics.se>. More information can be obtained
+at the uIP homepage at http://www.sics.se/~adam/uip/.
+
+This is version $Name: uip-1-0 $.
+
+The directory structure look as follows:
+
+apps/ - Example applications
+doc/ - Documentation
+lib/ - Library code used by some applications
+uip/ - uIP TCP/IP stack code
+unix/ - uIP as a user space process under FreeBSD or Linux

+* A new API: protosockets that are similar to BSD sockets but does not
+ require any underlying multithreading system.
+
+* Very rudimentary IPv6 support
+
+* New application: DHCP client. Web server rewritten with protosockets.
+
+* Removed uIP zero-copy functionality in order to simplify uIP device
+ driver coding: outbound packets are now *always* stored in full in
+ the uip_buf buffer.
+
+* Checksum computation is now part of uip.c, but it still is possible
+ to implement them in assembly code by specifying a configuration
+ option. Checksum code now runs on architectures with 2-byte alignment.
+
+* Added TCP persistent timer.
+
+* Made all IP address representations use the new uip_ipaddr_ip
+ datatype for clarity.
+
+* Updated window behavior so that sending to a host with a small open
+ window works better now.
+
+* UDP API change: uip_udp_new() now takes port numbers in network byte
+ order like TCP functions.
+
+* Allow reception of packets when no IP address is configured to make
+ DHCP work.
+
+* Moved Ethernet address into main uIP module from ARP module.
+
+* Made constants explicit #defines and moved them out of the code
+ (header sizes, TCP options, TCP header length field).
+
+* If uip_len is less than that reported by the IP header, the packet
+ is discarded. If uip_len is greater than the length reported by the
+ IP header, uip_len is adjusted.
+
+* Moved header size definitions into header file.
+
+* Added uIP call for polling an application without triggering any
+ timer events. Removed redundant assignments of uip_len and uip_slen.
+
+* Removed compiler warning about icmp_input label being defined when
+ UIP_PINGADDRCONF was not used.
+
+* Added UIP_APPDATA_SIZE macro that holds the available buffer size
+ for user data.
+
+* Added uip_udp_bind() call.
+
+* Moved checksum code into main uIP module.
+
+* Switched the TCP, UDP and IP header structures to be structs rather
+ than typedefs.
+
+* Prefixed TCP state names with UIP_ to avoid name space
+ contamination.
+
+* Changed declarations of uip_appdatap and friends to void * to avoid
+ explicit typecasts.
+
+* Bugfixes
+
+ o TCP: Fixed bug with high byte of peer window size.
+
+ o TCP: Fixed bug that in some cases prevented concurrent reception and
+ transmission of TCP data.
+
+ o TCP: uip_connect() didn't correctly calculate age of TIME_WAIT
+ connections.
+
+ o TCP: Array index for uip_conns[] array was out of bounds in
+ comparison. Comparison changed to make index within bounds.
+
+ o TCP: if the remote host crashes and tries to reestablish an old
+ connection, uIP should respond with an ACK with the correct
+ sequence and acknowledgment numbers, to which the remote host
+ should respond with an ACK. uIP did not respond with the correct
+ ACK.
+
+ o TCP: Fixed check for SYNACK segment: now checks only relevant TCP
+ control flags and discards flags reserved for future expansion.
+
+ o TCP: Fixed bug where uIP did not inform application that a connection
+ had been aborted during an active open.
+
+ o TCP: FIN segment was accepted even though application had stopped
+ incoming data with uip_stop().
+
+ o TCP: A FINACK segment would not always correctly acknowledge data.
+
+ o UDP: checksums are now calculated after all fields have been
+ filled in.
+
+ o UDP: network byte order on lastport in uip_udp_new().
+
+ o IP: memset() bugs in IP fragment reassembly code fixed.

+/**
+ * \defgroup psock Protosockets library
+ * @{
+ *
+ * The protosocket library provides an interface to the uIP stack that is
+ * similar to the traditional BSD socket interface. Unlike programs
+ * written for the ordinary uIP event-driven interface, programs
+ * written with the protosocket library are executed in a sequential
+ * fashion and does not have to be implemented as explicit state
+ * machines.
+ *
+ * Protosockets only work with TCP connections.
+ *
+ * The protosocket library uses \ref pt protothreads to provide
+ * sequential control flow. This makes the protosockets lightweight in
+ * terms of memory, but also means that protosockets inherits the
+ * functional limitations of protothreads. Each protosocket lives only
+ * within a single function. Automatic variables (stack variables) are
+ * not retained across a protosocket library function call.
+ *
+ * \note Because the protosocket library uses protothreads, local
+ * variables will not always be saved across a call to a protosocket
+ * library function. It is therefore advised that local variables are
+ * used with extreme care.
+ *
+ * The protosocket library provides functions for sending data without
+ * having to deal with retransmissions and acknowledgements, as well
+ * as functions for reading data without having to deal with data
+ * being split across more than one TCP segment.
+ *
+ * Because each protosocket runs as a protothread, the protosocket has to be
+ * started with a call to PSOCK_BEGIN() at the start of the function
+ * in which the protosocket is used. Similarly, the protosocket protothread can
+ * be terminated by a call to PSOCK_EXIT().

+ * \defgroup uipsplit uIP TCP throughput booster hack
+ * @{
+ *
+ * The basic uIP TCP implementation only allows each TCP connection to
+ * have a single TCP segment in flight at any given time. Because of
+ * the delayed ACK algorithm employed by most TCP receivers, uIP's
+ * limit on the amount of in-flight TCP segments seriously reduces the
+ * maximum achievable throughput for sending data from uIP.
+ *
+ * The uip-split module is a hack which tries to remedy this
+ * situation. By splitting maximum sized outgoing TCP segments into
+ * two, the delayed ACK algorithm is not invoked at TCP
+ * receivers. This improves the throughput when sending data from uIP
+ * by orders of magnitude.
+ *
+ * The uip-split module uses the uip-fw module (uIP IP packet
+ * forwarding) for sending packets. Therefore, the uip-fw module must
+ * be set up with the appropriate network interfaces for this module
+ * to work.

+ * uIP is a small implementation of the IP, UDP and TCP protocols (as
+ * well as some basic ICMP stuff). The implementation couples the IP,
+ * UDP, TCP and the application layers very tightly. To keep the size
+ * of the compiled code down, this code frequently uses the goto
+ * statement. While it would be possible to break the uip_process()
+ * function into many smaller functions, this would increase the code
+ * size because of the overhead of parameter passing and the fact that
+ * the optimier would not be as efficient.
+ *
+ * The principle is that we have a small buffer, called the uip_buf,
+ * in which the device driver puts an incoming packet. The TCP/IP
+ * stack parses the headers in the packet, and calls the
+ * application. If the remote host has sent data to the application,
+ * this data is present in the uip_buf and the application read the
+ * data from there. It is up to the application to put this data into
+ * a byte stream if needed. The application will not be fed with data
+ * that is out of sequence.
+ *
+ * If the application whishes to send data to the peer, it should put
+ * its data into the uip_buf. The uip_appdata pointer points to the
+ * first available byte. The TCP/IP stack will calculate the
+ * checksums, and fill in the necessary header fields and finally send
+ * the packet back to the peer.
