[PATCH 00/12] add packet generator library and example app

[Ronan Randles]

This patchset introduces a Gen library for DPDK. This library provides an easy
way to generate traffic in order to test software based network components.

This library enables the basic functionality required in the traffic generator.
This includes: raw data setting, packet Tx and Rx, creation and destruction of a
 Gen instance and various types of data parsing.
This functionality is implemented in "lib/gen/rte_gen.c". IPv4 parsing
functionality is also added in "lib/net/rte_ip.c", this is then used in the gen
library.

A sample app is included in "examples/generator" which shows the use of the gen
library in making a traffic generator. This can be used to generate traffic by
running the dpdk-generator generator executable. This sample app supports
runtime stats reporting (/gen/stats) and line rate limiting
(/gen/mpps,<target traffic rate in mpps>) through telemetry.py.

As more features are added to the gen library, the sample application will
become more powerful through the "/gen/packet" string parameter
(currently supports IP and Ether address setting). This will allow every
application to generate more complex traffic types in the future without
changing API.

Harry van Haaren (6):
  gen: add files for initial traffic generation library
  gen: add basic Rx and Tx routines and tests
  gen: add raw packet data API and tests
  gen: add parsing infrastructure and Ether protocol
  gen: add gen IP parsing
  examples/generator: import code from basicfwd.c

Ronan Randles (6):
  net: add string to IPv4 parse function
  net: add function to pretty print IPv4
  examples/generator: enable gen library for traffic gen
  examples/generator: telemetry support
  examples/generator: link status check added
