Hi,

first of all: Please avoid sending HTML messages to this list.
Moreover your text part is hard to read, because of the strange

The problem is, that the network driver does not register at the master
module in your case. Did you set the correct address in the sysconfig
file?

You're right, the documentation is a little bit out of date. I
aplologize. But this will change in the next release, that is already on

Please use the supplied makefile. A kernel modules has to be built, so
a simple call of gcc is not sufficient.
