[dts] [PATCH for-next v3 0/7] Fixes and modifications for T-Rex integration and nic_single_core_perf

[Patrick MacArthur <pmacarth@iol.unh.edu>]

The first four patches of this series are bug fixes necessary to run the
nic_single_core_perf test in its current state in the UNH-IOL
environment.

Patch 5 automates starting T-Rex as part of the prepare_generator()
setup step, if the "start_trex" configuration option is enabled.

Patch 6 adds a section to the DTS getting started guide which describes
how T-Rex should be configured for relevant tests.

Patch 7 adds JSON output to the nic_single_core_perf test, which can be
more easily consumed by automated tools.

This patch set targets the next branch, and I have uploaded these
patches to our local open-source git server:

  tests/TestSuite_nic_single_core_perf: Report the results in JSON format (2018-03-29 14:54:21 -0400)

Patrick MacArthur (7):
  framework/texttable: Update to latest upstream version
  framework: Do not attempt ping6 on T-Rex ports
  tests/TestSuite_nic_single_core_perf: Fix config parsing
  tests/TestSuite_nic_single_core_perf: Use user-specified output dir
  framework/pktgen: Start T-Rex during prepare_generator()
  doc: Add T-Rex section to documentation
  tests/TestSuite_nic_single_core_perf: Report the results in JSON
    format

Changes from v2:
 - Remove STLClient.resolve() call; assume that T-Rex is in Layer 2
   stateless mode.
 - Add trex section to manual describing expected Layer 2 stateless
   configuration.
 - Fix missing 'os' import (identified by Ali Alnubani).
 - Add JSON output file for use by UNH-IOL test lab.

Changes from v1:
 - Add a configuration option to pktgen.cfg; trex is only started by DTS
   if the option is present and non-empty.
 - Drop patch 6 which renamed the test case.
