Decouple rtnetlink address families from real address families in socket.h to be able to add rtnetlink interfaces to code that is not a real address family without increasing AF_MAX/NPROTO. This will be used to add support for multicast route dumping from all tables as the proc interface can't be extended to support anything but the main table without breaking compatibility. This partialy undoes the patch to introduce independant families for routing rules and converts ipmr routing rules to a new rtnetlink family. Similar to that patch, values up to 127 are reserved for real address families, values above that may be used arbitrarily. Signed-off-by: Patrick McHardy <kaber@trash.net>
