1This port contains infrastructure and examples for running lwIP on Unix-like 2operating systems (Linux, OpenBSD, cygwin). Much of this is targeted towards 3testing lwIP applications. 4 5* port/sys_arch.c, port/perf.c, port/include/arch/: Generic platform porting, 6 for both states of NO_SYS. (Mapping debugging to printf, providing 7 sys_now & co from the system time etc.) 8 9* check: Runs the unit tests shipped with main lwIP on the Unix port. 10 11* port/netif, port/include/netif: Various network interface implementations and 12 their helpers, some explicitly for Unix infrastructure, some generic (but most 13 useful on an easy to debug system): 14 15 * fifo: Helper for sio 16 17 * list: Helper for unixif 18 19 * pcapif: Network interface that replays packages from a PCAP dump file, and 20 discards packages sent out from it 21 22 * sio: Mapping Unix character devices to lwIP's sio mechanisms 23 24 * tapif: Network interface that is mapped to a tap interface (Unix user 25 space layer 2 network device). Uses lwIP threads. 26
