Leonid,
There is no doubt NAPI helping interrupts mitigation, throughput, packets out of order and balance between latency and throughput. But NAPI might not help all of the devices since different drivers have different implementations for CQ completion handler.
I am working on a patch to use multiple threads work queue for ipoib completion polling. Have you tried to this on your driver?
Thanks
