From a346abe051bd2bd0d5d0140b2da9ec95639acad7 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 1 Jul 2019 06:39:36 -0700 Subject: ipv6: icmp: allow flowlabel reflection in echo replies Extend flowlabel_reflect bitmask to allow conditional reflection of incoming flowlabels in echo replies. Note this has precedence against auto flowlabels. Add flowlabel_reflect enum to replace hard coded values. Signed-off-by: Eric Dumazet Signed-off-by: David S.
