I guess this also applies to the 3.16 kernel as well; I dropped both
patches earlier:

 3d0ad09412ff drivers/net: Disable UFO through virtio
 5188cd44c55d drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO packets

but I should have kept the second one.  I'll queue it again for the
next release.
