Hi Viktor,
I sent a new version patch set, and please have a look at them.

Well, I tried. But setsockopt() needs a fd, and before nl_connect(), we cannot
use nl_socket_get_fd() to get the fd because the fd is allocated in nl_connect().
But if setsockopt() is called after nl_connect(), it doesn't work.
For now, I didn't find any better solution.

I tried my best to find all of them.
If I missed something, please tell me.
Thanks. :)
