Hello!
So question is, pktgen hooks in netif_wake_queue or let pktgen busy-spin?
My first instinct is to avoid the hook in general code and pktgen let spin
to only affect testing.
Ok. For my testing, I often run pktgen at slower speeds and need to run
other applications
with good performance as well, so it hurts to give pktgen an entire CPU
to just spin. I'm
going to go ahead and port over the no-spin logic and hooks, but I'll
try to keep that patch
easily separated from the rest of the changes I make to pktgen so
perhaps the other changes
can be incorporated.
Thanks,
Ben
Cheers.
