The libnl library itself is probably the best example that I have seen.  At 
it's core it is basically just regular Netlink with an extra layer of 
abstraction, i.e. a new header between the Netlink header and the payload.

Also, if you are still looking for in-kernel examples here are two _very_ 
simple ones which might help:

 * net/netlabel/netlabel_unlabeled.c:netlbl_unlabel_accept()
   This function reads a single attribute, NLBL_UNLABEL_A_ACPTFLG, sent
   from user space and acts on the value.

 * net/netlabel/netlabel_unlabeled.c:netlbl_unlabel_list()
   This function generates a reply message with a single attribute,
   NLBL_UNLABEL_A_ACPTFLG, in response to a request message.
