Subject: [PATCH net-next 2/2] samples: pktgen: new append mode
To configure various complex flows we for sure can create custom
pktgen init scripts, but sometimes thats not that easy.
New "-a" (append) option in all the existing sample scripts allows
to append more "devices" into pktgen threads.
The most straightforward usecases for that are:
- using multiple devices. We have to generate full linerate on
all physical functions (ports) of our multiport device.
- pushing multiple flows (with different packet options)

+"-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

+ # run joint traffic on two devs
