From 48670ed6f77adb44e696eb2b97592e25a2889fb6 Mon Sep 17 00:00:00 2001 From: Rami Rosen Date: Thu, 17 Jan 2019 13:39:26 +0200 Subject: [PATCH] doc: add missing loopback option in testpmd guide This patch adds a missing topology "loop" mode for port-topology option in testpmd guide. The testpmd "loop" option (PORT_TOPOLOGY_LOOP) was added to testpmd parameter port-topology back in 2014, but it seems that it was never added to the testpmd guide. This patch adds it in the testpmd guide.
