[openib-general] Interrupt Threshold Rate equivalent in Infiniband NIC

[harish]

Hi Roland,
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
