the krping test module make use of rdma_cm* apis. will
the module work with ib_cm* api?

You would have to adapt the module to use the ib_cm APIs.  The posting of the work requests is the same, however.


  should i using rdma_cm module or ib_cm module,
which is the standard?

Both are supported.  The rdma_cm will allow you to connect using IP addresses, and operates at a higher level.  For most applications, it is probably sufficient, and will be easier to work with.  With the ib_cm API, you will need to perform your own SA queries, and handle device hotplug yourself, but you avoid any connection abstraction.
