From 87ee9e52ffeb168803a76cc07734425227cc2268 Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Thu, 4 Jun 2015 09:16:44 -0700 Subject: net: Add IPv6 flow label to flow_keys In flow_dissector set the flow label in flow_keys for IPv6. This also removes the shortcircuiting of flow dissection when a non-zero label is present, the flow label can be considered to provide additional entropy for a hash.
