I see that a patch to add IPv6 support to the gre(7) interface(s)
was submitted, and became kern/29150.  I have just run into a need
for this support, and will be applying this patch or something very
much like it to my 2.0.2 tree.

   I wanted to investigate whether any work has been done to get
this incorporated into the trunk.  And if so, if it could be
pulled into netbsd-3 and possibly even netbsd-2.

   Thanks.  Let me know if you have any opinion or interaction
with this code.
