Subject: [dpdk-dev] [PATCH v7 05/10] app/test-pmd:test VxLAN packet identification
Date: Thu, 23 Oct 2014 21:18:55 +0800
Message-ID: <1414070340-19128-6-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1414070340-19128-1-git-send-email-jijiang.liu@intel.com>

Add two commands to test VxLAN packet identification.
The test steps are as follows:
 1> use commands to add/delete VxLAN UDP port.
 2> use rxonly mode to receive VxLAN packet.
