Subject: [PATCH V2] doc: add missing loopback option in testpmd guide
Date: Thu, 17 Jan 2019 13:39:26 +0200 [thread overview]
Message-ID: <1547725166-15070-1-git-send-email-ramirose@gmail.com> (raw)
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.
v2: Change "loopback" to "loop" (following Bernard review)
Fixes: 3e2006d6186c ("app/testpmd: add loopback topology")
