[dpdk-dev] [PATCH v3 2/3] examples/ip_pipeline: integrate TAP port

[Jasvinder Singh <jasvinder.singh@intel.com>]

The TAP port support is added to ip_pipeline app. To parse
configuration file with TAP port entries, parsing function is implemented.
The TAP ports configuration check and initialization routines have been
included in application code.
