+  EFI ARP Protocol Definition
+
+  The EFI ARP Service Binding Protocol is used to locate EFI
+  ARP Protocol drivers to create and destroy child of the
+  driver to communicate with other host using ARP protocol.
+  The EFI ARP Protocol provides services to map IP network
+  address to hardware address used by a data link protocol.

+  This function is used to insert entries into the ARP cache.
+
+  ARP cache entries are typically inserted and updated by network protocol drivers
+  as network traffic is processed. Most ARP cache entries will time out and be
+  deleted if the network traffic stops. ARP cache entries that were inserted
+  by the Add() function may be static (will not time out) or dynamic (will time out).
+  Default ARP cache timeout values are not covered in most network protocol
+  specifications (although RFC 1122 comes pretty close) and will only be
+  discussed in general terms in this specification. The timeout values that are
+  used in the EFI Sample Implementation should be used only as a guideline.
+  Final product implementations of the EFI network stack should be tuned for
+  their expected network environments.

+  @param  TargetSwAddress        Pointer to a protocol address to add (or deny).

+  @param  TimeoutValue           Time in 100-ns units that this entry will remain
+                                 in the ARP cache. A value of zero means that the

+                                state transition.
+  @param  Packet                The DHCP packet that is going to be sent or already received.

+  Adds and deletes routing table entries.
+
+  The Routes() function adds a route to or deletes a route from the routing table.
+
+  Routes are determined by comparing the SubnetAddress with the destination IPv4

+  on the same subnet as the configured station address.
+
+  The default route is added with SubnetAddress and SubnetMask both set to 0.0.0.0.
+  The default route matches all destination IPv4 addresses that do not match any
+  other routes.
+
+  A GatewayAddress that is zero is a nonroute. Packets are sent to the destination
+  IP address if it can be found in the ARP cache or on the local subnet. One automatic
+  nonroute entry will be inserted into the routing table for outgoing packets that
+  are addressed to a local subnet (gateway address of 0.0.0.0).
+
+  Each EFI IPv4 Protocol instance has its own independent routing table. Those EFI
+  IPv4 Protocol instances that use the default IPv4 address will also have copies
+  of the routing table that was provided by the EFI_IP4_CONFIG_PROTOCOL, and these
+  copies will be updated whenever the EIF IPv4 Protocol driver reconfigures its

+/**
+  Starts running the configuration policy for the EFI IPv4 Protocol driver.
+
+  The Start() function is called to determine and to begin the platform
+  configuration policy by the EFI IPv4 Protocol driver. This determination may
+  be as simple as returning EFI_UNSUPPORTED if there is no EFI IPv4 Protocol
+  driver configuration policy. It may be as involved as loading some defaults
+  from nonvolatile storage, downloading dynamic data from a DHCP server, and
+  checking permissions with a site policy server.
+  Starting the configuration policy is just the beginning. It may finish almost
+  instantly or it may take several minutes before it fails to retrieve configuration
+  information from one or more servers. Once the policy is started, drivers
+  should use the DoneEvent parameter to determine when the configuration policy
+  has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to
+  determine if the configuration succeeded or failed.
+  Until the configuration completes successfully, EFI IPv4 Protocol driver instances
+  that are attempting to use default configurations must return EFI_NO_MAPPING.
+  Once the configuration is complete, the EFI IPv4 Configuration Protocol driver
+  signals DoneEvent. The configuration may need to be updated in the future.
+  Note that in this case the EFI IPv4 Configuration Protocol driver must signal
+  ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default
+  configurations must return EFI_NO_MAPPING until the configuration policy has
+  been rerun.
+
+  @param  This                   The pointer to the EFI_IP4_CONFIG_PROTOCOL instance.
+  @param  DoneEvent              Event that will be signaled when the EFI IPv4
+                                 Protocol driver configuration policy completes
+                                 execution. This event must be of type EVT_NOTIFY_SIGNAL.
+  @param  ReconfigEvent          Event that will be signaled when the EFI IPv4
+                                 Protocol driver configuration needs to be updated.
+                                 This event must be of type EVT_NOTIFY_SIGNAL.
