From 25cfd5cac3ef31c8969db2efb067140cf4e7f08f Mon Sep 17 00:00:00 2001 From: Ethan Jackson Date: Tue, 15 Nov 2011 18:35:26 -0800 Subject: [PATCH] flow: flow_extract() improperly parses IPv6 TOS bits. This problem could cause userspace to automatically evict IPv6 flows from the datapath which had TOS bits set.
