From 4720106b99f76d32f71ad52f77bf79b60e070128 Mon Sep 17 00:00:00 2001 From: Jiaxin Wu Date: Thu, 25 Feb 2016 10:52:13 +0800 Subject: [PATCH] NetworkPkg: Change the default IPv6 config policy The default policy for Ip6Config is Ip6ConfigPolicyAutomatic, which results in all NIC ports starting SARR process when it receives RA message with M flag from IPv6 router. So, this patch is used to changes the the default IPv6 config policy to Ip6ConfigPolicyManualand also defer the SetData operation after Ip6ConfigProtocol installed. This update let the other platform drivers have chance to change the default config data by consume Ip6ConfigProtocol.
