We actually support this feature: commit df3687ffc6653e4d32168338b4dee20c164ed7c9 Author: Florent Fourcot <florent.four...@enst-bretagne.fr> Date: Fri Jan 17 17:15:03 2014 +0100 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. Bye, Hannes
