Jiaxin Wu ecbd055d4e MdeModulePkg/Ip4Dxe: Sync the direct route entry setting.
v2: use "IP & Netmask" directly instead of defining an additional variable.

This patch is to sync the direct route entry setting in both the default
and Instance route table {Subnet, Mask, NextHope} (
https://bugzilla.tianocore.org/show_bug.cgi?id=1143).

Jiaxin Wu bd0656b5e2 MdeModulePkg: Fix potential failure if UseDefaultAddress configured
IpSb->Reconfig should not be set to TRUE to focal the reconfiguration
during the policy changes from Static to DHCP. It's redundancy because
the default router table and default addresses have been freed ahead (
Detailed see Ip4Config2OnPolicyChanged() function). Otherwise, the
potential failure will appear if UseDefaultAddress configured. Reproduce
steps see below:

#1. Set policy to DHCP.
#2. If DHCP process is not complete yet, then run one APP to invoke UDP4
Configure with "UseDefaultAddress = TRUE" (loop to call UDP4 Configure
until Ip4Mode.IsConfigured changes to TRUE).
#3. Even DHCP succeed but Ip4Mode.IsConfigured flag never set to TRUE

Concrete analysis is as follows:
In #1, the policy will be set to DHCP, and then Ip4Config2OnPolicyChanged()
will be called. In this function, if "IpSb->Reconfig" flag is set to TRUE,
the original "IpSb->DefaultInterface" will be abandoned/freed once the
DHCP process finished.

In #2, UDP4 Configure with "UseDefaultAddress = TRUE" is called, that means
the default interface (IpSb->DefaultInterface) will be selected as current
instance's interface.

In #3, when DHCP process finished, the original DefaultInterface will be
abandoned/freed because "IpSb->Reconfig" flag is true. Meanwhile, one new
interface is assigned to "IpSb->DefaultInterface". This new interface is
different to the original one assigned to the UDP4 Configured instance. So,
even DHCP process succeed, the up caller will never have the chance to get
it's truly status.

Jiaxin Wu eab4016490 MdeModulePkg: Fix IPv4 stack potential disappeared issue
IP4_CONFIG2_INSTANCE->DataItem is used to save the configuration
data to NV variable. When the policy is changed from static to
DHCP, DnsServers info will be cleaned from DataItem first
(See Ip4Config2SetPolicy), it's correct because DnsServers info
should not be saved to NV variable.
But if there is any DnsServers info received from DHCP message, it
will be reset to DataItem again (See Ip4Config2SetDnsServerWorker),
which may cause the NV variable contain the DnsServers info while
the policy is DHCP (See Ip4Config2WriteConfigData).
Then, while the platform is reset, the issue happened. Because
Ip4Config2DataTypeDnsServer is set under DHCP policy, which is not
allowed by UEFI Spec and error returned.

This patch is used to resolve this potential issue.

Jiaxin Wu 5cb90e14e1 MdeModulePkg: Fix the wrong IpSb->State update
This patch is used to fix the wrong IpSb->State update issue.

Issue reproduce steps:
1 .First PXE boot, then boot to shell;
2. ifconfig -s eth0 dhcp (Success);
3. Reboot and do PXE, then boot to shell;
4. ifconfig -s eth0 dhcp (Platform failed to get IP address no matter
   how many times retried.)

Root cause:
On step3 reboot, policy is DHCP (Changed by step2). So, Ip4Dxe driver
will try to get one IP address from DHCP server automatically. Before
it get the IP address successfully, the IpSb->State will be always in
IP4_SERVICE_STARTED status until the Instance->Dhcp4Event is triggered,
then it can be changed to IP4_SERVICE_CONFIGED. But the DHCP process
will be interrupted by PXE boot, which will change the policy to static,
and the Instance->Dhcp4Event will be also closed directly. However,
current implementation doesn't update the IpSb->State to
IP4_SERVICE_UNSTARTED status in such case. So, failure happened.

Fix a possible ASSERT after NBP finishes loading from a PXE
boot. Ip4Dxe driver calls Ip4Config2SetPolicy which calls
CloseEvent on the Dhcp4Event struct member.  After NBP is
downloaded, it then calls Ip4Config2CleanInstance which calls
CloseEvent again on Dhcp4Event.  This double free can cause an
ASSERT. When the event is closed, set the event pointer to NULL
so the Ip4 code won't call CloseEvent on it again.

Jiaxin Wu 7648748e99 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.

Ip4Config2 protocol implementation must request for DNS server info when the
policy is set to DHCP. And when a DHCP server responds to it with a list of
DNS server addresses, it must parse it and set it for the instance. Without
this, nobody can do a Ip4Config->GetData for DNS server IPs before calling
Dns->Configure(). This will mean a DHCP is initiated when calling
Dns->Configure(), thus causing serious performance issues. This patch
attempts to address this issue.
