Pktgen: Created 2010-2020 by Keith Wiles @ Intel.com
Note: In DPDK 19.08-rc0 a large number of defines and function names were changed. In Pktgen 3.7.0 I added a pg_compat.h header to help compatibility issues with these name changes. This means versions 3.6.6 and below will have trouble building with DPDK starting with 19.08-rc0 or just after the 19.05 release.

run.sh is a script designed to help you with the command line options of pktgen.
You may need to modify this script for your system and configuration.

** Note: The '-m NNN' in the DPDK arguments is to have DPDK allocate 512 megs of memory. The '--socket-mem 256,156' DPDK command will allocate 256M from each CPU (two in this case). Do not use the '-m NNN' and '--socket-mem NN,NN' commands on the same command line.
** Note: As of DPDK 18.05 using -m or --socket-mem is not required as memory is now dynamically allocated.
The pktgen program follows the same format as a standard DPDK linux, meaning the first set of arguments '-l 0-4' are the standard DPDK arguments. This option defines the number of logical cores to be used by pktgen. The 1f states 5 lcores are used and the '3c' is just a bit array for each lcore to be used. The '-P' enables promiscuous mode on all ports if you need that support. The '-m "..."' sets up the port to lcore mapping for pktgen.
The second half of the command line followed by the '--' is pktgen specific options.
The pktgen requires 2 logical cores for a minimum system. The first lcore 0 used for pktgen command line and is used for timers also displaying the text on the screen and lcores 1-n are used to do the packet receive and transmits along with anything else related to packets. You do not need to start at lcore zero, but the first lcore in the bitmap from in the least signification bit location is the display and timer lcore used by pktgen.
The -m format now allows the developer to have different lcores for rx and tx instead of rx/tx on the same lcore. The above format of {1:3}.0 states to use lcore 1 for rx and lcore 3 for tx on port 0. Make sure you select different lcores for the rx and tx so that only a single rx or tx function is on a single physical core. If you pick the rx/tx functions on different lcores, but on the same physical core you will not be able to get the performance you want as the single physical core will be trying to do both Rx/Tx functions.
*** New setup and run python script with config files ***
Using the new tools/run.py script to setup and run pktgen with different configurations. The configuration files are located in the cfg directory with filenames ending in .cfg.
To use a configuration file;
$ ./tools/run.py -s default # to setup the ports and attach them to DPDK (only needed once per boot)
$ ./tools/run.py default # Run the default configuration
The configuration files are python scripts or a set of variables that run.py uses to initialize and run pktgen. Here is an example of the default.cfg file:

EAL: Detected 72 lcore(s)
./app/app/x86_64-dnet-linux-gcc/pktgen: invalid option -- 'x'
Usage: ./app/app/x86_64-dnet-linux-gcc/pktgen [options]
EAL common options:
-c COREMASK Hexadecimal bitmask of cores to run on
-l CORELIST List of cores to run on
The argument format is <c1>[-c2][,c3[-c4],...]
where c1, c2, etc are core indexes between 0 and 128
--lcores COREMAP Map lcore set to physical cpu set
The argument format is
'<lcores[@cpus]>[<,lcores[@cpus]>...]'
lcores and cpus list are grouped by '(' and ')'
Within the group, '-' is used for range separator,
',' is used for single number separator.
'( )' can be omitted for single element group,
'@' can be omitted if cpus and lcores have the same value
--initial-lcore ID Core ID that is used as initial
-n CHANNELS Number of memory channels
-m MB Memory to allocate (see also --socket-mem)
-r RANKS Force number of memory ranks (don't detect)
-b, --pci-blocklist Add a PCI device in block list.
Prevent EAL from using this PCI device. The argument
format is <domain:bus:devid.func>.
-w, --pci-allowlist Add a PCI device in allow list.
Only use the specified PCI devices. The argument format
is <[domain:]bus:devid.func>. This option can be present
several times (once per device).
[NOTE: PCI allowlist cannot be used with -b option]
--vdev Add a virtual device.
The argument format is <driver><id>[,key=val,...]
(ex: --vdev=net_pcap0,iface=eth2).
-d LIB.so|DIR Add a driver or driver directory
(can be used multiple times)
--vmware-tsc-map Use VMware TSC map instead of native RDTSC
--proc-type Type of this process (primary|secondary|auto)
--syslog Set syslog facility
--log-level Set default log level
-v Display version information on startup
-j Enable 9600 byte jumbo frames
-h, --help This help
EAL options for DEBUG use only:
--huge-unlink Unlink hugepage files after init
--no-huge Use malloc instead of hugetlbfs
--no-pci Disable PCI
--no-hpet Disable HPET
--no-shconf No shared config (mmap'd files)
EAL Linux options:
--socket-mem Memory to allocate on sockets (comma separated values)
--huge-dir Directory where hugetlbfs is mounted
--file-prefix Prefix for hugepage filenames
--base-virtaddr Base virtual address
--create-uio-dev Create /dev/uioX (usually done by hotplug)

A new feature for pktgen and DPDK is to run multiple instances of pktgen. This allows the developer to share ports on the same machine.

A command line passing in a pktgen/test/set_seq.pkt file to help initialize pktgen with some default values and configurations. You can also replace the filename using the '-f' command with a Lua script file ending in .lua instead of .pkt. BTW, if the filename ends in anything other then .lua it is treated as a .pkt file.
./app/pktgen -l 0-4 -n 3 --proc-type auto -- -P -m "[1:3].0, [2:4].1" -f test/set_seq.pkt

set all seqCnt 1
The set_seq.pkt command file can also be one of the files in pktgen/test directory, which are Lua based scripts instead of command line scripts as in set_seq.pkt file.
-- test/set_seq.lua The Lua version is easier to remember the layout of the agruments if you want to use that one instead of set_seq.pkt file.

Look at the two new files pktgen-initial.sh and pktgen-worker.sh for some help on the configuration to run two pktgens at the same time on the same machine.
-- Socket Support for Pktgen.
Pktgen has a TCP socket connection to allow you to control Pktgen from a remote program or console. The TCP connection is using port 0x5606 or 22022 and presents a Lua command shell interface. If you telnet to the machine running Pktgen on port 22022 you will get a lua command shell like interface. This interface does not have a command line prompt, but you can issue Lua code or load script files from the local disk of the machine. You can also send programs to the remote Pktgen machine to load scripts from a remote location.
One method to connect to Pktgen is using telnet, but another method would be to use 'socat' program on a Linux machine. The socat program is very powerfull application and can do a lot of things. I used socat to debug Pktgen using the following command, which gives me a readline inteface to Pktgen's socket interface.
$ socat -d -d READLINE TCP4:localhost:22022
'You will see socat create the connection and then wait for Lua command scripts for you' To exit this command type Control-D to exit and close the connection.
You can also just send Pktgen a script file and display the ouptut.

Hello World!!!!
Here is the program I sent Pktgen:
$ cat test/hello-world.lua
package.path = package.path ..";?.lua;test/?.lua;app/?.lua;"
printf("Lua Vesrion: %s\n", pktgen.info.Lua_Version);
printf("Pktgen Version : %s\n", pktgen.info.Pktgen_Version);
printf("Pktgen Copyright : %s\n", pktgen.info.Pktgen_Copyright);
printf("Pktgen Authors : %s\n", pktgen.info.Pktgen_Authors);
printf("\nHello World!!!!\n");
Here is a command from my Mac Book pro laptop, which loads a file from the local disk where Pktgen is running and then we execute the file with 'f()'.
$ socat READLINE TCP4:172.25.40.163:22022
