[ofw] librdmacm.dll PD

[Prasanna Kumar]

Hi All,

The current implementation of rdma_cm makes it necessary for PD to be 
allocated for every connection. But I think underlaying  WinVerbs can 
support single PD across multiple connections for a given IB device. 
Please let me know if I am correct.

One possible fix I think that can make rdma_cm to support single PD 
across multiple connections is to  initialize device in 'cma_dev_array' 
variable only once  in ucma_acquire() call and maintain same verbs 
pointer for all the cma_id created for a given IB device.
Please let me know your feedback on the same.

Thanks,
Prasanna
