Hi All,
I just noticed some strange behavior with the tg3 driver.
Even with NAPI enabled, during high loads of 1500 byte MTUS, I'm seeing a very
high interrupt rate. To move 500kBytes/sec I'm seeing 22k interrupts/sec. It
tracks very closely with the actualy throughput.
That amounts to about 1 interrupt per 23 bytes. I figured with NAPI, we should
do a lot better than that.
Is there a tuneable or some driver stat that I can track to figure out what's
happening here? I'd like to see that interrupt number be a lot lower.
