From 0a473b82cb23e7a35c4be6e9765c8487a65e8f55 Mon Sep 17 00:00:00 2001 From: Craig Gallek Date: Wed, 19 Apr 2017 12:30:53 -0400 Subject: ip6_tunnel: Allow policy-based routing through tunnels This feature allows the administrator to set an fwmark for packets traversing a tunnel. This allows the use of independent routing tables for tunneled packets without the use of iptables. Signed-off-by: Craig Gallek Signed-off-by: David S.
