From a81278b11de6393390816c8b3b675a313cd0ce9f Mon Sep 17 00:00:00 2001 From: Martin Klozik Date: Mon, 7 Mar 2016 09:52:22 +0000 Subject: bugfix: Cleanup of traffic gen api and default traffic values Both documentation and traffic generator API are updated to match current code logic. Additional default values are added into TRAFFIC_DEFAULTS dictionary. Constructor of TestCase class uses default values from TRAFFIC_DEFAULTS instead of magic numbers.
