    It's a matter on how far you want to go.
    There are many MMU and GPL less solutions available.
    The following can be considered as the other extrem end:
    uIP, lwIP, Nut/OS, ...
    Just having the essential to run network based services.
    There is very much room of what people might expect from systems
    with more features.
