+Sample and benchmark scripts for pktgen (packet generator)
+==========================================================
+This directory contains some pktgen sample and benchmark scripts, that
+can easily be copied and adjusted for your own use-case.
+
+General doc is located in kernel: Documentation/networking/pktgen.rst
+
+Helper include files
+====================
+This directory contains two helper shell files, that can be "included"
+by shell source'ing. Namely "functions.sh" and "parameters.sh".
+
+Common parameters
+-----------------
+The parameters.sh file support easy and consistant parameter parsing
+across the sample scripts. Usage example is printed on errors::
+
+ Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
+ -i : ($DEV) output interface/device (required)
+ -s : ($PKT_SIZE) packet size
+ -d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
+ -m : ($DST_MAC) destination MAC-addr
+ -p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed
+ -t : ($THREADS) threads to start
+ -f : ($F_THREAD) index of first thread (zero indexed CPU number)
+ -c : ($SKB_CLONE) SKB clones send before alloc new SKB
+ -n : ($COUNT) num messages to send per thread, 0 means indefinitely
+ -b : ($BURST) HW level bursting of SKBs
+ -v : ($VERBOSE) verbose
+ -x : ($DEBUG) debug
+ -6 : ($IP6) IPv6
+ -w : ($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
+ pg_ctrl start
+
+Common functions
+----------------
+The functions.sh file provides; Three different shell functions for
+configuring the different components of pktgen: pg_ctrl(), pg_thread()
+and pg_set().
+
+These functions correspond to pktgens different components.
+ * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
+ * pg_thread() control the kernel threads and binding to devices
+ * pg_set() control setup of individual devices
+
+See sample scripts for usage examples.
