samples: pktgen: new append mode

2021-03-14T21:22:38Z

To configure various complex flows we for sure can create custom pktgen init scripts, but sometimes thats not that easy. New "-a" (append) option in all the existing sample scripts allows to append more "devices" into pktgen threads. The most straightforward usecases for that are: - using multiple devices. We have to generate full linerate on all physical functions (ports) of our multiport device. - pushing multiple flows (with different packet options) Signed-off-by: Igor Russkikh Signed-off-by: David S.

DELAY may now be explicitly specified via common parameter -w Signed-off-by: Igor Russkikh Signed-off-by: David S. Miller

docs: networking: convert pktgen.txt to ReST

2020-04-30T19:56:37Z

- add SPDX header; - adjust title markup; - use bold markups on a few places; - mark code blocks and literals as such; - adjust identation, whitespaces and blank lines where needed; - add to networking/index.rst. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: David S. Miller

samples: pktgen: allow to specify destination IP range (CIDR)

2019-10-07T13:26:32Z

Currently, kernel pktgen has the feature to specify destination address range for sending packet. (e.g. pgset "dst_min/dst_max") But on samples, each pktgen script doesn't have any option to achieve this. This commit adds the feature to specify the destination address range with CIDR. -d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed # ./pktgen_sample01_simple.sh -6 -d fe80::20/126 -p 3000 -n 4 # tcpdump ip6 and udp 05:14:18.082285 IP6 fe80::99.71 > fe80::23.3000: UDP, length 16 05:14:18.082564 IP6 fe80::99.43 > fe80::23.3000: UDP, length 16 05:14:18.083366 IP6 fe80::99.107 > fe80::22.3000: UDP, length 16 05:14:18.083585 IP6 fe80::99.97 > fe80::21.3000: UDP, length 16 Signed-off-by: Daniel T.

samples: pktgen: allow to specify destination port

2019-07-01T18:02:20Z

Currently, kernel pktgen has the feature to specify udp destination port for sending packet. (e.g. pgset "udp_dst_min 9") But on samples, each of the scripts doesn't have any option to achieve this. This commit adds the DST_PORT option to specify the target port(s) in the script. -p : ($DST_PORT) destination PORT range (e.g. 433-444) is also allowed Signed-off-by: Daniel T.

pktgen: Specify the index of first thread

2017-06-16T16:32:34Z

Use "-f ", to specify the index of the first sender thread. In default first thread is #0. Signed-off-by: Tariq Toukan Cc: Jesper Dangaard Brouer Acked-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

pktgen: Specify num packets per thread

2017-06-16T16:32:34Z

Use -n , to specify the number of packets every thread sends. Zero means indefinitely. Signed-off-by: Tariq Toukan Cc: Jesper Dangaard Brouer Acked-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

pktgen: new pktgen helper functions for samples scripts

2015-05-23T03:59:16Z

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 Signed-off-by: David S.
