     *   This plugin starts software execution using VS_ST_MAC; despite
     *   an affirmative respond from the device, there is no guarantee
     *   that the firmware will actually start or continue to run so we
     *   wait for a response and report the result;
     *
     *   struct nvm_header1 must be little-endian order and ready to send
