inet_proto_csum_replace16() wants a non NULL checksum pointer to update,
and there is no such thing here.
I could pass a dummy value, but inet_proto_csum_replace16() will do
twice mo

With this setup:
* non IPv6 checksumming capable network hardware
* GRO off
* IPv6 SNAT
I get this when I receive an UDPv6 reply: ": hw csum failure"
Call trace:
* nf_ip6_checksum() calls __skb_checksum_complete()
* nf_nat_ipv6_csum_update() & nf_nat_ipv6_manip_pkt()
* __udp6_lib_rcv() => udp6
