The IPv6 router has nothing to do anymore with checksums, they are all
handled in upper layers, so that the router does not have to recalculate
checksums for packets it handles. The checksum will be checked by the
end host and this host will initiate resend mechanisms. If I recall
correctly it has been done to reduce router CPU load.
