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. +*/ + +#include "uip.h" +#include "uipopt.h" +#include "uip_arch.h" + +#if UIP_CONF_IPV6 +#include "uip-neighbor.h" +#endif /* UIP_CONF_IPV6 */ + +#include + +/*---------------------------------------------------------------------------*/ +/* Variable definitions. */ + + +/* The IP address of this host.
