Unfortunately, this feature is not defined by RIO spec. This is
proprietary function, so we
cannot rely on it. Yes, this is nice feature of Tsi57x switches and may
be used if you have
a closed system - just enable it in em_init. The RIO spec part 8 is
quite open about port-write generation and we cannot expect the same
behavior from different devices.
