IPv6 IPsec tunnel gateway incorrectly sends redirect to
router or sender when network device the IPsec tunnelled packet
is arrived is the same as the one the decapsulated packet
is sent.
With this patch, it omits to send the redirect when the forwarding
skbuff carries secpath, since such skbuff should be assumed as
a decapsulated packet from IPsec tunnel by own.
It may be a rare case for an IPsec security gateway, however
it is not rare when the gateway is MIPv6 Home Agent since
the another tunnel end-point is Mobile Node and it changes
the attached network.
