It seems reasonable and that's what I was thinking when you submitted the patch to use TXOk. I think NAPI could be used with either TxOK or TxIdle interrupts. For TxIdle to work, the driver would have to recognize one more packet is still in flight and poll for completion of that packet - then re-enable interrupts and switch back to interrupt mode of operation. I just don't know if netperf TCP_RR perf numbers will suffer (assuming TCP_RR is more important than CPU utilization/efficiency on heavy TX loads like pktgen.) grant - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
