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