From da610604b81292497f3b60d31b04cfb78c2bad03 Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Thu, 30 Mar 2017 16:29:54 +0800 Subject: [PATCH] net/i40e: enable tunnel filter for MPLS MPLSoUDP & MPLSoGRE is not supported by tunnel filter due to limited resource of HW, this patch enables MPLS tunnel filter by replacing inner_mac filter. This configuration will be set when adding MPLSoUDP and MPLSoGRE filter rules, and it will be invalid only by NIC core reset.
