This port contains infrastructure and examples for running lwIP on Unix-like operating systems (Linux, OpenBSD, cygwin). Much of this is targetted towards testing lwIP applications. * port/sys_arch.c, port/perf.c, port/include/arch/: Generic platform porting, for both states of NO_SYS. (Mapping debugging to printf, providing sys_now & co from the system time etc.) * check: Runs the unit tests shipped with main lwIP on the Unix port. * port/netif, port/include/netif: Various network interface implementations and their helpers, some explicitly for Unix infrastructure, some generic (but most useful on an easy to debug system): * fifo: Helper for sio * list: Helper for unixif * pcapif: Network interface that replays packages from a PCAP dump file, and discards packages sent out from it * sio: Mapping Unix character devices to lwIP's sio mechanisms * tapif: Network interface that is mapped to a tap interface (Unix user space layer 2 network device). Uses lwIP threads.
