Not stable, still under development...

A unified network driver for Cortex-M: brings up Ethernet/LwIP, runs client and server tasks, manages connections and disconnections, and provides a clean API to the application.

• FreeRTOS: separate tasks for server dispatcher, client dispatcher, interface input task, and one task per connection/session.

• Semaphores/IRQ: ETH interrupt triggers net__irq(), driver signals semaphore pvSmphrInput, input task consumes frame and passes it to LwIP.

• Link state: callback in net.c tracks previous state, updates flags, and shuts down all servers on down.

1. Call net__init(&net).
2. Register servers/clients with net__add_srv() / net__add_clt() using a filled net_init_t and your own net_if_fn_t set.
3. Run net__run(&net) — dispatchers and input task will start; sessions will spawn automatically as connections are made.

• Add a couple of examples (a number are available yet but not prepared)
• Add wrappers for thread calls and thus get support for various RTOS not only FreeRTOS
• Do a deep code refactoring and add support of Linux
