[dpdk-dev] [PATCH v3 2/7] examples/ip_pipeline: modifies common pipeline CLI

[Piotr Azarewicz <piotrx.t.azarewicz@intel.com>]

From: Tomasz Kulasek <tomaszx.kulasek@intel.com>

All link commands are merged into one command:
cmd_link_parsed.
Improve run command to allow run periodically.
Adding static keyword to a lot of token declarations.
