Could someone take a look at PR kern/35897 and perhaps do something
about it?

There is (and has been since the KAME code was added) an ioctl that
cannot possibly (I believe) work.   It should be deleted (it clearly
isn't actually used, and when I submitted the PR I did a complete search of
all the NetBSD sources to check that nothing was attempting to use it.)

It really would be nice to have this cleaned up and pulled up to NetBSD 4
before that gets released (the PR has been languishing for 6 months now).
