From 3aa4a6fab319a1e532eb8bb963a4632bc37797ef Mon Sep 17 00:00:00 2001 From: Christian Trautman Date: Mon, 23 Jan 2017 13:33:56 -0500 Subject: xena_cont_learning: Adds learning preemption to continuous traffic Adds a configurable learning preemptive option when running xena continuous traffic tests. This resolves a missing packet or two when running OVS tests at flow rates that should not drop packets.
