Hi,
I got it all finally everything working with "setsockopt" as suggested.

In case anybody else wants to experiment with connector, I attach my
examples (maybe add it to Documentation/connector/?)

Anyway - there are two more issues (not bugs) which I'd like to solve:
- When sending message from kernel, cn_netlink_send returns an error
in case when there is no reciever - BUT user space "send" doesn't
return an error when there is no reciever in kernel :-(

- How (if) can I do ACK (acknoledge received and processed message)?

Thanks for your help,
Libor Vanek
