【infiniband_diags tool question】

[oulijun]

Hi, Jason Gunthorpe
    I have noticed that you have integrated infiniband_diags in the new rdma-core repo.
I want to try to using it in RoCE. it is fail. the print as flows:
roo
root@(none)# ./ibaddr -g 0
 ibwarn: [1054] mad_rpc_open_port: client_register for mgmt 1 failed
  Failed to open (null) port 0

I found through process analysis that it needs ca to support IB_QPT_SMI.
I understand that if hca does not support SMI, then we will not be able to use infiniband_diags tool?

Thanks
Lijun Ou

I didn't think diags were really relevant for roce? The only thing
that should work is perfquery

This is correct.   infiniband-diags are not really relevant to RoCE or OPA.
While some tools will work.  They are not specifically designed for nor
intended to support anything other than InfiniBand.
