When netlink is used with recvmsg/sendmsg, so when decoding these
messages, we already know that they will this will be netlink packets.

So a good start would be to just decode the basic headers for these
packets, only on recvmsg/sendmsg, and build from there in order to add
more protocols for example.

After that we need also to be able to look at send/recv, but for that
we need to be able to recognize the protocol before. There may be some
work done on that point (retrieve the address family/type/protocol
under a socket) but I am not sure about it.

I hope this answers your interrogations, and helps you in order to
create a proposal.
