+/** @file

+  Load File protocol as defined in the UEFI 2.0 specification.

+

+  Load file protocol exists to supports the addition of new boot devices, 

+  and to support booting from devices that do not map well to file system. 

+  Network boot is done via a LoadFile protocol.

+

+  UEFI 2.0 can boot from any device that produces a LoadFile protocol.

+  @retval EFI_SUCCESS           The file was loaded.

+  @retval EFI_DEVICE_ERROR      The file was not loaded due to a device error.

+  @retval EFI_NO_RESPONSE       The remote system did not respond.

+  @retval EFI_NOT_FOUND         The file was not found

+  @retval EFI_ABORTED           The file load process was manually canceled.

+  @retval EFI_BUFFER_TOO_SMALL  The BufferSize is too small to read the current
