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.
