From f463c563912abb806fe0d2fe85a4cf6825f416cc Mon Sep 17 00:00:00 2001 From: Dino Simeon Madarang Date: Mon, 19 Oct 2015 14:55:06 +0100 Subject: Add OVS tunnel encapsulation performance test Measure OVS DPDK and native VXLAN/GRE/GENEVE encapsulation performance. This patch creates a new deployment scenario, Overlay_P2P. The DUT is configured as a TEP (Tunnel Endpoint) which performs encapsulation of frames and sends traffic to the 2nd traffic generator port. The traffic generator in this case receives an encapsulated frame. No decapsulation is performed in this testcase. Introduce a vsperf param, --run-integration, to filter tests to integration tests. When running integration tests, variables defined in the directory conf/integration/*conf as well as the conf/*.conf are available. This test case requires DPDK 2.1.0 and OVS master - 6bb4a18 or newer.
