Patch for tun(4) w/ IPv6
There's a patch to make tun(4) understand IPv6
on the (german language!) JOIN IPv6 mailing list.
A follow-up also mentions that there is a patch (#29150) in the PR queue
that add IPv6 to gre(4).
Just in case someone needs this, and until this gets
(hopefully soon... :/) integrated into NetBSD.
