[lng-odp] odp_hash_crc32 support

[Daniel Feferman]

Hi All,

I saw on this link:

https://www.opendataplane.org/api-documentation/master/api/group__odp__hash.html#ga9ecafbeec4af9a0cd93311a1ee324725

That odp has support to Calculate CRC-32 without Castagnoli. I've tried so
many ways and I was not able to do so. Then, I saw an example using Castagnoli,
I've tried to implement it and using Castagnoli worked. So, I'd like to
double check, does ODP (still) has support to Calculate CRC-32 without
Castagnoli?

Best,
Daniel

NAME
   odp_generator – generate or terminate IPv4 traffic

SYNOPSIS
   odp_generator OPTIONS

DESCRIPTION
   This ODP example application generates or terminate IPv4
traffic and outputs statistic prints at 20 s interval time

  Work mode:
-   generate UDP packets (‘u’ mode): IPv4 UDP packets are
generated with configured payload size, IP addresses, UDP ports, etc.
e.g.
  odp_generator -I  -m u --srcmac   --dstmac  --srcip  --dstip 

-   receive IPv4 packets (‘r’ mode): IPv4 packets are received at
highest rate.
e.g.
  odp_generator -I  -m r

-   generate/receive ICMP (ping) packets (‘p’ mode): requires two cores
e.g.
  odp_generator -I  -m p --srcmac  --dstmac  --srcip  --dstip  --cpumask 

Mandatory OPTIONS:

  -I, --interface Eth interfaces (comma-separated, no spaces)
  -m, --mode work mode: generate udp(u), receive(r), generate/receive icmp(p)
  -a, --srcmac  (‘udp’, ‘icmp’) Source MAC address
  -b, --dstmac (‘udp’, ‘icmp’) Destination MAC address
  -s, --srcip (‘udp’, ‘icmp’) Source IP address
  -d, --dstip (‘udp’, ‘icmp’) Destination IP address

Optional OPTIONS

  -h, --help   Display help and exit.
  -e, --srcport (‘udp’) Source UDP port
  -f, --dstport (‘udp’) Destination UDP port
  -p, --packetsize (‘udp’, ‘icmp’) Payload length of generated packets
  -t, --timeout (‘icmp’) Wait ICMP reply timeout seconds
  -i, --interval (‘udp’, ‘icmp’) Wait interval ms between sending each
packet burst
 default is 1000 ms. 0 for flood mode
  -w, --workers Specify number of workers to be assigned to application
 default is to assign all. On ‘icmp’ mode, number of
workers is forced to 2.
  -c, --cpumask Specify number of workers and distribution on cores as
hexadecimal value
  -n, --count (‘udp’, ‘icmp’) The number of packets to be generated
  -x, --udp_tx_burst (‘udp’) Size of UDP TX burst
  default is 16
  -r, --rx_burst (‘receive’) Size of RX burst
  default is 32
  -y, --csum Use platform checksum support if available
 default is disabled
  -z, --sched (‘receive’) Use scheduler API to receive packets instead
of direct mode API.
 default is direct mode API

Re: [lng-odp] odp tools manpages

[Bogdan Pricope]

Start from 'help' option of odp_generator:

# ./example/generator/odp_generator -h

Usage: odp_generator OPTIONS
  E.g. odp_generator -I eth1 -r

OpenDataPlane example application.

  Work mode:
1.send ipv4 udp packets
  odp_generator -I eth0 --srcmac fe:0f:97:c9:e0:44  --dstmac
32:cb:9b:27:2f:1a --srcip 192.168.0.1 --dstip 192.168.0.2 -m u
2.receive ipv4 packets
  odp_generator -I eth0 -m r
3.work likes ping
  odp_generator -I eth0 --srcmac fe:0f:97:c9:e0:44  --dstmac
32:cb:9b:27:2f:1a --srcip 192.168.0.1 --dstip 192.168.0.2 --cpumask
0xc -m p

Mandatory OPTIONS:
  -I, --interface Eth interfaces (comma-separated, no spaces)
  -a, --srcmac src mac address
  -b, --dstmac dst mac address
  -s, --srcip src ip address
  -d, --dstip dst ip address
  -m, --mode work mode: send udp(u), receive(r), send icmp(p)

Optional OPTIONS
  -h, --help   Display help and exit.
  -e, --srcport src udp port
  -f, --dstport dst udp port
  -p, --packetsize payload length of the packets
  -t, --timeout only for ping mode, wait ICMP reply timeout seconds
  -i, --interval wait interval ms between sending each packet
 default is 1000ms. 0 for flood mode
  -w, --workers specify number of workers need to be assigned to application
 default is to assign all
  -n, --count the number of packets to be send
  -c, --cpumask to set on cores
  -x, --udp_tx_burst size of UDP TX burst
  -r, --rx_burst size of RX burst
  -y, --csum use platform checksum support if available
 default is disabled
  -z, --sched use scheduler API to receive packets
 default is direct mode API

It needs some update.

Re: [lng-odp] odp tools manpages

[Maxim Uvarov]

shouldn't it be man page for odp library which we somehow can generate from
doxygen?

Where do you package odp examples? I think they have to be somewhere under
/usr/share/bin/odp-examples and just referenced as example apps. (Like QT
examples do). Rather then be "tools".

[lng-odp] odp tools manpages

[Dmitry Eremin-Solenikov]

Hello,

To finish ODP packaging work I have to provide manpages for ODP tools
that are going to be packages. I've written manpages for odp_hello and
odp_crypto, however
I'm asking for the help in writing manpages for l2fwd/l3fwd/generator.
Could you please help me by sketching clean descriptions of what these
tools do, that I can put into manpage?
