[dpdk-dev] [PATCH 32/40] net/ice/base: enable QinQ filter for switch advanced rule
Qi Zhang

Mon Sep 7 13:28:18 CEST 2020
Enable QinQ type filter for switch advanced rule, it support tunnel
and non-tunnel packet use external and inner vlan id as input set
for rules, it also support session id as input set for PPPoE rule
with QinQ flag in packet.
