Correct.
At the moment its used for two things - the netlink route interface allows a
routing daemon (read gated one day) to monitor interface/kernel routing
shifts without continaully scanning /proc/net/route and /proc/net/dev.
The other test use is part of the SKIP authentication package. And you can
find others as you like. It also exports its symbols to modules.
