Subject: [dpdk-dev] [PATCH v5 05/10] examples/tep_termination:add UDP port configuration for UDP tunneling packet
Date: Tue, 23 Jun 2015 00:41:00 +0800	[thread overview]
Message-ID: <1434991265-20384-6-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1434991265-20384-1-git-send-email-jijiang.liu@intel.com>

The port number of UDP tunneling packet is configurable.

For i40e, it has 16 entries in total.
