From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rami Rosen Subject: [PATCH] doc: add missing loopback option in testpmd guide Date: Thu, 17 Jan 2019 11:31:13 +0200 Message-ID: <1547717473-7213-1-git-send-email-ramirose@gmail.com> Cc: stable@dpdk.org, john.mcnamara@intel.com, Rami Rosen To: dev@dpdk.org Return-path: List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" This patch adds a missing topology loopback mode for port-topology option in testpmd guide. The testpmd loopback 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.
