Then this does not > matter? It would be queried for each end port LID but should provide same response on each port. Note that switch only has port 0 as end port. It looks to me that in the query that the port supplied overwrites ClassVersion field in supplied ClassPortInfo attribute which is MAD data offset 41 where PortSelect goes. ClassPortInfo.ClassVersion is a RO field and should be ignored by the PMA in the query and set properly in the response so yes, you're right that it should not matter. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
