Preparing for removing existing samples/pktgen/ scripts, and replacing these with easier to use samples. This commit provides two helper shell files, that can be "included" by shell source'ing. Namely "functions.sh" and "parameters.sh". The parameters.sh file support easy and consistant parameter parsing across the sample scripts. Usage example is printed on errors. The functions.sh file provides, three new shell functions for configuring the different components of pktgen: pg_ctrl(), pg_thread() and pg_set(). A slightly improved version of the old pgset() function is also provided for backwards compat. The new 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 These changes are borrowed from: https://github.com/netoptimizer/network-testing/tree/master/pktgen Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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.
