From 9123de2c043996050bacf77031cad845f5976f5d Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 20 Sep 2006 11:59:42 -0700 Subject: [PATCH] [NETFILTER]: ip6table_mangle: reroute when nfmark changes in NF_IP6_LOCAL_OUT Now that IPv6 supports policy routing we need to reroute in NF_IP6_LOCAL_OUT when the mark value changes.
