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

[Hal Rosenstock]

Roland,
 
Just to close the loop on this:
 
Are those the only component fields which were zeroed out ?
 
Thanks.
 
-- Hal

I think Yael figured it out:
Looking at Roland's code it seems like it will not filter out the
PortRecords coming from switch physical ports. So actually he gets many
records that all have base lid = 0 and gid = 0 from these ports...

I assume this is the case. There is no trivial way to know from the
PortInfo in the PortRecord to which type of node the port belongs. Only
a combination of NodeRecord PortRecord (by base lid) can tell you if the
PortRecord is an HCA port or switch port.
