From 7648748e99eeeadec38fda7568adb260c4acc861 Mon Sep 17 00:00:00 2001 From: Jiaxin Wu Date: Thu, 25 Feb 2016 10:48:58 +0800 Subject: [PATCH] MdeModulePkg: Change the default IPv4 config policy Git version '3d0a49ad' commit provided a scenario to resolve the performance issue for IPv4, but it's not workable for IPv6. To avoid IPv4 and IPv6 inconsistency, we decided to revert that version fix. If so, the default policy for Ip4Config2 is Ip4Config2PolicyDhcp, which results in all NIC ports attempting DHCP. So, this patch is used to changes the the default IPv4 config policy to Ip4Config2PolicyStatic and also defer the SetData operation after Ip4Config2Protocol installed. This update let the other platform drivers have chance to change the default config data by consume Ip4Config2Protocol.
