From df3687ffc6653e4d32168338b4dee20c164ed7c9 Mon Sep 17 00:00:00 2001 From: Florent Fourcot Date: Fri, 17 Jan 2014 17:15:03 +0100 Subject: ipv6: add the IPV6_FL_F_REFLECT flag to IPV6_FL_A_GET With this option, the socket will reply with the flow label value read on received packets. The goal is to have a connection with the same flow label in both direction of the communication. Changelog of V4: * Do not erase the flow label on the listening socket. Use pktopts to store the received value Signed-off-by: Florent Fourcot Acked-by: Hannes Frederic Sowa Signed-off-by: David S.
