- 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.txt
- 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 : ($DEST_IP) destination IP
- -m : ($DST_MAC) destination MAC-addr
- -t : ($THREADS) threads to start
- -c : ($SKB_CLONE) SKB clones send before alloc new SKB
- -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.
