/**
Update the parameters of a TFTP boot option
The function asks sequentially to update the IPv4 parameters as well as the boot file path,
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
"BdsLoadOptionTftpCreateDevicePath()" function.
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
