   BTW, It seems in_stf_input() had bugs...

Can you elaborate?  Your change to if_stf.c doesn't look quite right:
you've made in_stf_encapsw follow the IPv6 input prototype, but it's
still an IPv4/AF_INET protocol as it should be -- stf(4) encapsulates
IPv6 packets inside IPv4 packets on the wire.

One thing that this explicit prototype business doesn't check,
unfortunately, is whether the AF_* that you passed to encap_attach
matches the .encapsw* member of the union that you initialized.
