    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    Have you tried the obvious - examine existing kernel drivers?
    Sometimes, real fast is almost as good as real time.

    Yes, I look to different driver example (snull, loopback,..) but I am trying to write the network driver that transmit packets through netlink socket`s. I don't have any experience on Linux drive I just need sample example so I can build my according to it

    I'm talking about existing network drivers. There is root network code that all network device drivers use. You REALLY need to get familiar with all that. Download the source for your kernel, install it, and start looking at that. In the kernel tree, there is a top-level directory "net" that has all this cruft. This is not simple stuff, but you should be able to figure it out with some effort. The netlink driver is there also in net/netlink.
