Because of this, it will take some time to detangle the licensing under net/. Many new features, original features were added to the NuttX network. Clearly, any references to Adam Dunkels in the files that implement these new features that have no counterpart in uIP 1.0 are errors. This PR removes the references and converts the license headers to Apache 2.0 where possible. The affected files include only (1) the implementation of IPv6 (including neighbor support under ICMPv6) and (2) Raw sockets. Neither of these features are present in uIP 1.0 and the licenses can be freely updated.
