Subject: [PATCH v3 2/2] net/i40e: improve packet type parser
Date: Thu,  4 Jan 2018 18:46:21 +0800	[thread overview]
Message-ID: <1515062781-49210-3-git-send-email-beilei.xing@intel.com> (raw)
In-Reply-To: <1515062781-49210-1-git-send-email-beilei.xing@intel.com>

Add support for PPPoE and L2TP packet types parser.
Change parser as new metadata 'OIPV4' and 'OIPV6'
added in profile to distinguish outer IP and inner
IP.
