sendto() EPERM errors

Bug description:
SRU Justificaton:
[Impact]
Users of ipvs may encounter dropped packets and message such as:
[70325.516724] IPv6 header not found
[Fix]
Commit eb90b0c734ad793d5f5bf230a9e9a4dcc48df8aa.
[Regression Potential]
This changes NFPROTO_IPV4 to NFPROTO_IPV6 as we'd expect this nf_hook_ops
struct to be in the code.

I have an Ubuntu 14.04 host that I am using as both a keepalived/ipvs
loadbalancer and dnsmasq server for pxebooting servers.
After updating linux-image 3.13.0-29.53 -> 3.13.0-32.57 I noticed that
dnsmasq-tftp stopped working. pxeboot clients would hang on the
"Loading ..../linux" TFTP transfer, with the transfer stalling roughly
~1000 blocks into the transfer:
10:30:51.011728 IP 10.1.1.2.43540 > 10.1.12.1.49165: UDP, length 1412
10:30:51.011924 IP 10.1.12.1.49165 > 10.1.1.2.43540: UDP, length 4
10:30:51.012012 IP 10.1.1.2.43540 > 10.1.12.1.49165: UDP, length 1412
10:30:51.012183 IP 10.1.12.1.49165 > 10.1.1.2.43540: UDP, length 4
stracing dnsmasq I noticed something very odd: sendto() on the
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) would suddenly start
persistently returning EPERM in mid-transfer, even when dnsmasq
continued to periodically retry:

This was with all iptables rules unloaded (so no OUTPUT -j DENY) and
apparmor profiles torn down.
I also noticed the following dmesgs appearing at roughly similar times
to the tftp transfers getting stuck (although not coinciding exactly
with the stall):
[70325.516724] IPv6 header not found
The error pointed to ipvs (which I am using on the same host as an IPv4 NAT
loadbalancer):
http://archive.linuxvirtualserver.org/html/lvs-devel/2012-08/msg00018.html
http://comments.gmane.org/gmane.comp.linux.lvs.devel/3614
I then tore down the ipvs rules (service keepalived stop) and unloaded
the modules (rmmod ip_vs_rr ip_vs), and the issue resolved itself -
the stalled dnsmasq-tftp transfer resumed!
This seems to be reproducible, i.e. modprobing ip_vs and starting
keepalived will cause dnsmasq-tftp to stall again, and
stopping/unloading will resume.
This seems to happen reproducibly on boot with -32 and -30. This does NOT
seem to happen with 3.13.0-29 which I was using up until now.
