[dpdk-dev] [PATCH 20.11 7/7] net/ice/base: support L4 for QinQ switch filter

[Wenjun Wu]

From: Steve Yang <stevex.yang at intel.com>

This patch is not for LTS upstream, just for users to cherry-pick.

This patch adds more dummy packet types for QinQ packet,
it enables tcp/udp layer of ipv4/ipv6 for QinQ payload,
so we can use L4 dst/src port as input set for switch
filter.

For Example:
    flow create 0 ingress pattern eth / vlan tci is 2 / vlan tci is 1 \
    / ipv4 src is 196.222.232.221 / tcp src is 400 / end actions queue \
    index 1 / end
