openweave-esp32-lwip | LwIP enhanced to support Nest OpenWeave

lwIP is a small independent implementation of the TCP/IP protocol suite that has been developed by Adam Dunkels at the Computer and Networks Architectures (CNA) lab at the Swedish Institute of Computer Science (SICS). The focus of the lwIP TCP/IP implementation is to reduce the RAM usage while still having a full scale TCP. This making lwIP suitable for use in embedded systems with tens of kilobytes of free RAM and room for around 40 kilobytes of code ROM. lwIP is freely available under a BSD license. lwIP has grown into an excellent TCP/IP stack for embedded devices, and developers using the stack often submit bug fixes, improvements, and additions to the stack to further increase its usefulness. Development of lwIP is hosted on Savannah, a central point for software development, maintenance and distribution. Everyone can help improve lwIP by use of Savannah's interface, Git and the mailing list. A core team of developers will commit changes to the Git source tree. The lwIP TCP/IP stack is maintained in the 'lwip' Git module and contributions (such as platform ports) are in the 'contrib' Git module. See doc/savannah.txt for details on Git server access for users and developers. The current Git trees are web-browsable: http://git.savannah.gnu.org/cgit/lwip.git http://git.savannah.gnu.org/cgit/lwip/lwip-contrib.git. Submit patches and bugs via the lwIP project page: http://savannah.nongnu.org/projects/lwip/. The original out-dated homepage of lwIP and Adam Dunkels' papers on lwIP are at the official lwIP home page: http://www.sics.se/~adam/lwip/. Self documentation of the source code is regularly extracted from the current Git sources and is available from this web page: http://www.nongnu.org/lwip/. There is now a constantly growin wiki about lwIP at http://lwip.wikia.com/wiki/LwIP_Wiki. Also, there are mailing lists you can subscribe at http://savannah.nongnu.org/mail/?group=lwip plus searchable archives: http://lists.nongnu.org/archive/html/lwip-users/ http://lists.nongnu.org/archive/html/lwip-devel/. Reading Adam's papers, the files in docs/, browsing the source code documentation and browsing the mailing list archives is a good way to become familiar with the design of lwIP.
