The following patchset V2 makes IPVS compatible with Patrick McHardys
IPv6 NAT patchset: http://thread.gmane.org/gmane.linux.network/239615

Specifically the part that improves defragmentation.

 Patch01: Cleanup (and fixes a bug) in IPVS MTU IPv6 handling
  In V2: we also handle tunnel mode, to use the common helper

 Patch02: Extend MTU check to account for IPv6 NAT defrag changes
  In V2: the tunnel mode is no longer a special case.

This patchset is based upon:
 Homes ipvs-next tree:
  git://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next.git

BUT with Patrick McHardy's IPv6 NAT patchset applied first, on top of
commit: 3654e61137db891f5312e6dd813b961484b5fdf3
title: "ipvs: add pmtu_disc option to disable IP DF for TUN packets"
