Like Ralf already said: __initfunc(...) just puts the following code into a
special text section which gets freed after initialization. This has nothing to
do with the circumstances under which your code is beeing called.

If you want to do some experiments with a net driver you may want to edit
drivers/net/Space.c accordingly.  

Hope this helps.
