From 11556c915a0847d742d5e1823f03035667f99871 Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Thu, 4 Jan 2018 18:46:21 +0800 Subject: [PATCH] net/i40e: improve packet type parser 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.
