Hi Roland,<br><br>As regards the CQ notification frequency, I noticed that the function req_ncomp_notif used by ib_req_ncom_notif is not implemented yet. I was hoping that if this was implemented, I would just use ib_req_ncom_notif with a count of 10 in place of ib_req_com_notif. Please share your comments on this approach and it will be great if you have a patch with the ib_req_ncom_notif implementation.

harish> Hi Roland, Thanks a lot for the prompt response. Could you<br> harish> please let me know as to what is the expected time frame<br> harish> for having NAPI for IPoIB implemented. Also as regards to
<br> harish> the first question, would it make sense to play around<br> harish> with the cq notification frequency. Will it help to reduce<br> harish> the CPU utilization/ interrupt overhead?<br><br>I can't tell you when NAPI will be implemented, since I don't know if
<br>anyone is working on it.<br><br>You could try playing around with the CQ notification frequency but if<br>you're going to hack the driver then I think it would be just as easy<br>to implement NAPI. Anyway, give it a try and let us know your results.
<br><br>Thanks,<br> Roland<br></blockquote></div><br>
