Hi,
We are running Pktgen on two seperate VMs. We use a range of src mac
addresses to create a certain amount of flows. We have noticed that there
is a ~8K flow limit per VF bonded to the VM. It is basically a limit of 8K
src macs that create a flow for each port/VF. Is this a Pktgen limit? Is
there a way to achieve more flows per VF bonded to the VM?

Kind regards
Jaco Gericke

In Pktgen this is a limit to the amount of memory allocated per port for the range command. You can increase the number by increasing the define in the file app/pktgen-constants.h and increase the number of packets per port. Increasing these numbers will consume memory very quickly so be be careful.
