What is your kernel config in regards to HRES timers? Robert mentioned
to me that the clock source maybe causing issues with pktgen (maybe even
qos).
Robert, insights?
In my case, I have:
# CONFIG_TICK_ONESHOT is not set
# CONFIG_NO_HZ is not set
# CONFIG_HIGH_RES_TIMERS is not set
I will try to turn on those in a few days and see if notice a
difference.
Again, thanks Evgeniy.
cheers,
jamal
