[openib-general] SRP device management client (and a few opensmglitches)

[Eitan Zahavi]

Hi Roland,

Now I get it ! 
In the port info record there is a field named LocalPortNumber. 
This field is NOT the port number the data is about.
It is the port number the packet of the query came from.
(see table 145 p823 l-38).
When OpenSM obtains the PortInfo associated with that particular port it
did so through port 2 of the switch. So the LocalPortNum is set to 2.

If you are interested with the real port number, it is located in the
RID second field, of the PortInfoRecord returned by the SA GetTable
query.

Hope this helps.
