Thanks a lot for the prompt response. Could you please let me know as to what is the expected time frame for having NAPI for IPoIB implemented. Also as regards to the first question, would it make sense to play around with the cq notification frequency. Will it help to reduce the CPU utilization/ interrupt overhead?
Sincerely thanks again,
Harish

There is no such equivalent for IB.
However I am thinking about implementing NAPI for IPoIB, which should
help in your situation.
