From 50374442032ed9cf1d5d9069dfd856bb4c9008c5 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Mon, 23 Sep 2019 15:44:27 +0800 Subject: [PATCH] net/ice/base: support switch rule about VLAN PPPoE Add support for switch rule about single-VLAN-PPPoE. Note that double VLAN is not supported by the hardware at this point, therefore only single-VLAN support for PPPoE is added.
