[dpdk-dev] [PATCH v6 3/5] net/ice: support switch flow for specific L4 type

[Wei Zhao]

This patch add more specific tunnel type for ipv4/ipv6 packet,
it enable tcp/udp layer of ipv4/ipv6 as L4 payload but without
L4 dst/src port number as input set for the switch filter rule.

Fixes: 47d460d63233 ("net/ice: rework switch filter")
