functions.sh	samples: pktgen: add helper functions for IP(v4/v6) CIDR parsing This commit adds CIDR parsing and IP validate helper function to parse single IP or range of IP with CIDR. (e.g. 198.18.0.0/15) Validating the address should be preceded prior to the parsing. Helpers will be used in prior to set target address in samples/pktgen. Signed-off-by: Daniel T.

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 : ( $D E V) o u t p u t i n t e r f a c e / d e v i c e (r e q u i r e d) - s : ($ 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 : ( $C O U N T) n u m m e s s a g e s t o s e n d p e r t h r e a d, 0 m e a n s i n d e f i n i t e l y - b : ($ BURST) HW level bursting of SKBs -v : ( $V E R B O S E) v e r b o s e - x : ($ 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.
