From 38b7097b55b6cf30adc5ac07cb1055683224393e Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Sat, 11 Jun 2016 20:08:19 +0200 Subject: ipv6: use TOS marks from sockets for routing decision In IPv6 the ToS values are part of the flowlabel in flowi6 and get extracted during fib rule lookup, but we forgot to correctly initialize the flowlabel before the routing lookup.
