  Starts running the configuration policy for the EFI IPv4 Protocol driver.\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
