For base port 0 (BSP0), port state is not used. For enhanced port 0 (ESP0), it behaves like a TCA. I would expect that on reset, the port would be INIT and require the SM to walk it up to ACTIVE but once there it would likely remain there. I don't know if this impacts the patch incorporated or not or whether this discussion is an aside to that. -- Hal > -- Yevgeny > >> Sasha _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
