>Environment:
Enable INET6 And setting up INET6 routing.
>Description:
        V6 enviroment was completed. And after setting up tun device
for V6. creating a static routeing information by

        od -h /dev/tun0 &
        route add -inet6 default -interface tun0

And execute

        ping6 -I tun0 fe80::1

At normal case. V6 packet was routed into interface tun0. But packet was
rejected before tun device.
        So problem dose exist on initializing routine. if tun device
is staticaly network interface, Seem to be no problem. But it is not.
Must execute a initializing routine "in6_ifattach" directly.


>How-To-Repeat:
        Open and configure some tun for v6. And send some v6 packet
which is routed into tun device.

>Fix:
This is a diffs for net/if_tun.c

begin 644 if_tun.c.diff
