From 3d26403053022e58a424984c5796a794505c91ec Mon Sep 17 00:00:00 2001 From: Ace Lee Date: Fri, 21 Jul 2017 03:02:04 +0000 Subject: [PATCH] support more parameters in iperf3 testcase JIRA: YARDSTICK-755 The parameters that iperf3 testcase support now maybe insufficient in some usecase. The test case should support parameters such as: windows size and length of buffer. This work is about adding more parameters that can be specified in options section in the YAML file.
