Yup :) These are netlink sockets with some data from the krenel.

Strictly speaking, we should patch the kernel to be able to peek
this data from socket and to put it back. But maybe in some cases
we could invent some workaround (I'm not quite sure netdev@ people
would be happy with such hacks :) ).

Can we investigate what kind of socket is it and what data is in
there?

Thanks,
