[dpdk-dev] [PATCH v3 37/69] net/ice/base: correct UDP/TCP PTYPE assignments

1. Using the UDP-IL PTYPEs when processing packet segments as it contains
all PTYPEs with UDP and allow packets to be forwarded to associated VSIs
as switch rules are based on outer IPs.
2. Add PTYPE 0x088 to TCP PTYPE bitmap list.
