Subject: linux-next: net tree build failure

Hi Dave,

Today's linux-next build (powerpc allyesconfig) failed like this:

net/ipv4/ipvs/ip_vs_proto_tcp.c: In function 'tcp_snat_handler':
net/ipv4/ipvs/ip_vs_proto_tcp.c:208: error: implicit declaration of function 'csum_ipv6_magic'
net/ipv4/ipvs/ip_vs_proto_udp.c: In function 'udp_snat_handler':
net/ipv4/ipvs/ip_vs_proto_udp.c:219: error: implicit declaration of function 'csum_ipv6_magic'

Introduced by commit 0bbdd42b7efa66685b6d74701bcde3a596a3a59d ("IPVS:
Extend protocol DNAT/SNAT and state handlers") which added a call to
csum_ipv6_magic but didn't include net/ip6_checksum.h.  I applied the
following patch.
