I have a really hard time accepting a "fix" that depends upon behavior that the Linux ipv6 stack doesn't even have.

ipv6: add the IPV6_FL_F_REFLECT flag to IPV6_FL_A_GET
Add that time I tried to stick to the common practices at that time and
was against any kind of global sysctl enabling a reflection mode for
flowlabels. State of art was to keep some uniqueness in flowlabels, thus
also the introduction of the flowlabel_consistency label.
We basically can support reflection nowadays globally pretty easy, as we
have soften these rules a lot.
