From: Alex Gartrell Date: Wed, 16 Jul 2014 22:57:34 +0000 (-0700) Subject: ipvs: Maintain all DSCP and ECN bits for ipv6 tun forwarding X-Git-Tag: firefly_0821_release~3679^2~1418 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=787fcb84098e4f9fdea75d777f010229c393690d;p=firefly-linux-kernel-4.4.55.git ipvs: Maintain all DSCP and ECN bits for ipv6 tun forwarding commit 76f084bc10004b3050b2cff9cfac29148f1f6088 upstream. Previously, only the four high bits of the tclass were maintained in the ipv6 case. This matches the behavior of ipv4, though whether or not we should reflect ECN bits may be up for debate.
