Legacy Networking Libraries

This is an mbed 2 networking library. For mbed OS 5, lwip has been integrated with built-in networking interfaces. The networking libraries have been revised to better support additional network stacks and thread safety here.

This library is based on the code of lwIP v1.4.0
