Reviewing this version, I noticed the absence of one mitigation that we should probably be recommending.

- in section 4.4. "Stateless Load Balancers" add the remark that balancers that use *only* the IPv6 Source Address, IPv6 Destination Address and IPv6 Flow Label (when it is non-zero) work perfectly on fragmented traffic.

- in section 7. "Recommendations" add a subsection "To Load Balancer Developers and Operators" saying that load balancers (including ECMP/LAG) SHOULD be designed and configured to use *only* the IPv6 Source Address, IPv6 Destination Address and IPv6 Flow Label (when it is non-zero).
