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. JIRA: VSPERF-473 Change-Id: I056578ed9c9181287d97aea55a002f09aac14e81 Signed-off-by: Christian Trautman <ctrautma@redhat.com>
