- Update the parameters of a TFTP boot option

- providing the previously set value if any.
-
- @param[in] OldDevicePath Current complete device path of the Tftp boot option.
- This has to be a valid complete Tftp boot option path.
- By complete, we mean that it is not only the Tftp
- specific end part built by the

- This path is handled as read only.
- @param[in] FileName Description of the file the path is asked for
- @param[out] NewDevicePath Pointer to the new complete device path.
-
- @retval EFI_SUCCESS Update completed
- @retval EFI_ABORTED Update aborted by the user
- @retval EFI_OUT_OF_RESOURCES Fail to perform the update due to lack of resource
