+ -w : ($DELAY) Tx Delay value (ns)
+ -a : ($APPEND) Script will not reset generator's state, but will append its config
The global variable being set is also listed. E.g. the required
interface/device parameter "-i" sets variable $DEV.
+"-a" parameter may be used to create different flows simultaneously.
+In this mode script will keep the existing config, will append its settings.
+In this mode you'll have to manually run traffic with "pg_ctrl start".
+
+For example you may use:
+
+ source ./samples/pktgen/functions.sh
+ pg_ctrl reset
+ # add first device
+ ./pktgen_sample06_numa_awared_queue_irq_affinity.sh -a -i ens1f0 -m 34:80:0d:a3:fc:c9 -t 8
+ # add second device
+ ./pktgen_sample06_numa_awared_queue_irq_affinity.sh -a -i ens1f1 -m 34:80:0d:a3:fc:c9 -t 8
+ # run joint traffic on two devs
