Yes, I've tried all pktgen modes.

Thank you. I will take a look at it.


  Pktgen Lua scripting is really used to control Pktgen and not
generate packets on the fly. Pktgen has a number of modes single,
range, random, PCAP, sequence, which could be used with an external
switch to merge the different TX options to a single target. I assume
using an external switch maybe not work very well here.
