As I already tried to explain, C++ in the kernel is *not* usable that 
way now until we have real shared libraries, at least not if you want 
to implement the net stack as a module.
You can't export a C++ API in modules, and therefore, you can't inherit 
from a class defined in a module - C++ can currently only be used per 
module, but not really inter-modular :)

Furthermore, with a C API you can implement your modules in both, C and 
C++ - with a C++ API you force all add-ons to be written in C++, and 
that's certainly something I don't want to do at this point.

Adios...
