/** @file\r
  The EFI_FORM_BROWSER_PROTOCOL is the interface to the EFI\r
  Configuration Driver.  This will allow the caller to direct the\r
  configuration driver to use either the HII database or use the passed\r
  in packet of data.  This will also allow the caller to post messages\r
  into the configuration drivers internal mailbox.\r
