Re: [v6ops] Operational Implications of IPv6 Packets with Extension Headers

Why isn't the flow label reliable, now that it's set by the major client
o/s? But I agree, server load balancing is severely broken if the balancer
is incapable of parsing the header chain. That's a design error in the
balancer. See RFC7098 for discussion.
