But why?  IMHO, NLMSG_* just add an uneccessary wrapper for messages
that can't ever have multiple parts.  I don't see it as a clean
interface in this case.

And are netlink(3) and netlink(7) really accurate for
NETLINK_FIREWALL?  They seem to concentrate on NETLINK_ROUTE.  For
example, both man pages refer to libnetlink which only supports
NETLINK_ROUTE.

Should NLMSG_* be used by netfilter targets for all kinds of netlink
messages over NETLINK_FIREWALL or NETLINK_NFLOG type sockets?
