When determining if the L4 checksum in an IPv6 packet can be offloaded on transmit, call ipv6_skip_exthdr_no_rthdr to check for the presence of a routing header. If a routing header is present, that is the function return less than zero, then don't offload checksum and call skb_checksum_help instead.
