From 545a5fac5d6bd0b64693dfcb15b321280418ac13 Mon Sep 17 00:00:00 2001 From: Pablo de Lara Date: Wed, 9 Jul 2014 15:35:36 +0100 Subject: [PATCH] ring: simplify unit tests Upstream-Status: Backport Imported patch from: http://dpdk.org/browse/dpdk/log/ As this unit test does not create devices anymore, and uses devices created by EAL option --vdev, there were unnecesary tests that were repeated, so they have been removed. So now there are three tests: 1 - Test two devices that share a ring, one device with just one RX queue and the other with one TX queue. 2 - Test a device connected to itself (loopback) by a ring, with both RX and TX queue. 3 - Test two devices that share a ring, but both devices with RX and TX queue, so they can send packets to themselves and to the other device.
