Subject: ipvs: Maintain all DSCP and ECN bits for ipv6 tun forwarding
From: Alex Gartrell <agartrell@xxxxxx>
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.
