Hi Marek,

If you ask, whether kernel supports a netlink family that allows you to
do that, then I don't know. I'd think there is none (?).


If you already know which netlink family you can use to achieve what
you want and whether libnl supports that, then the answer is:

libnl3 consists of a basic parsing library for netlink. You could use
that to help you parsing any kind of netlink protocol.
Then there are separate parts of the library (e.g. libnl-route-3.so),
which can help you handling a specific netlink protocol.
