--- Comment #30 from Kyle Evans <kevans at freebsd.org> ---
r346602 probably fixes the ip6_purgeaddr panic noted here. The tun mtx is
dropped while we purge addresses/routes and the TUN_OPEN flag was cleared,
giving tundestroy a chance to rototill the interface somewhere in the middle of
that.

I've opened https://reviews.freebsd.org/D20027 to try and settle the ioctl
race.
