[dpdk-dev] [PATCH v3 4/5] app/testpmd: add jansson library

[Viacheslav Ovsiienko <viacheslavo@nvidia.com>]

From: Gregory Etelson <getelson@nvidia.com>

Testpmd interactive mode provides CLI to configure application
commands. Testpmd reads CLI command and parameters from STDIN, and
converts input into C objects with internal parser.
The patch adds jansson dependency to testpmd.
With jansson, testpmd can read input in JSON format from STDIN or input
file and convert it into C object using jansson library calls.
