Hi Harry, I noticed as part of series_6218 (http://patches.dpdk.org/project/dpdk/list/?series=6218) that the travis build had a single failure, in service_autotest but it doesn't seem related to the series at all.
https://travis-ci.com/ovsrobot/dpdk/jobs/230358460 Not sure if there's some kind of debugging we can add or look at to help diagnose failures when they occur. Do you have time to have a look? -Aaron
