I think some protocols register some data to be sent in with each of the
netlink calls.  Netlink will sent this data in via the (void*).
MPLS doesn't need netlink to hold any data for it. So we do not use the (void*).

Since all of the netlink functions must match the netlink prototype
I have no choice but to have the (void*) argument.
