Subject: [dpdk-dev] [PATCH v7 03/10] librte_ether:add VxLAN packet identification API
Date: Thu, 23 Oct 2014 21:18:53 +0800
Message-ID: <1414070340-19128-4-git-send-email-jijiang.liu@intel.com> (raw)
In-Reply-To: <1414070340-19128-1-git-send-email-jijiang.liu@intel.com>

There are "some" destination UDP port numbers that have unque meaning.
In terms of VxLAN, "IANA has assigned the value 4789 for the VXLAN UDP port, and this value SHOULD be used by default as the destination UDP port. Some early implementations of VXLAN have used other values for the destination port. To enable interoperability with these implementations, the destination port SHOULD be configurable."

Add two APIs in librte_ether for supporting UDP tunneling port configuration on i40e.
Currently, only VxLAN is implemented in this patch set.
