[ Upstream commit0f0c4f1b72] Currently, "sample04" and "sample05" are not working properly when running with an IPv6 option("-6"). The commit0f06a6787e("samples: Add an IPv6 "-6" option to the pktgen scripts") has omitted the addition of this option at "sample04" and "sample05". In order to support IPv6 option, this commit adds logic related to IPv6 option.

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 The global variable being set is also listed. E.g. the required interface/device parameter "-i" sets variable $DEV. 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.
