Re: Regarding bottlenecks for high speed packet generation

Hi,

If the driver uses NAPI [1] / the chip supports that, then not. You
can observe the hardware / software interrupts via ifpps or watching
procfs or some other tools, or simply look at the driver
implementation.

But does NAPI comes into picture in case of transmission of packets ?
I read it comes into picture
only in the case of reception of packets.
