From 6895bba12f952ef8925e14d404aa1ab2184ffd8f Mon Sep 17 00:00:00 2001 From: "Sridhar K. N. Rao" Date: Tue, 16 Oct 2018 10:41:30 +0530 Subject: Results: Default latency-histrogram with Spirent TestCenter The patch adds support to provide Latency histogram from Spirent traffic generator. 1. 03_traffic.conf: Enable histogram, and set type (default) 2. testcenter.py: If histogram enabled, call the script with right flag. 3. testcenter-rfc2544-rest.py: configure and write histogram to a separte file in the default results folder. 4. Fix PyLint Errors 5. Adding a patch to test the 'build-error-fix'. Increased the MAX_MEMSEG of in DPDK-config to 1024 6. Adding MAX_MEMSEG configuration at common_base didn't work. 7. Included packet sizes in the output. 8. Included description under spirent TGen 9. Removed MAX_MEMSEG configuration.
