Actually, the new PCTYPE are not exposed to user in DPDK. Please not how
You deal with them.

[dpdk-dev] [PATCH] drivers/i40e: Add new PCTYPE for x722 hardware driver

[Jeff Guo]

There are 6 new PCTYPE be enabled in the i40e hardware driver
for x722, add them to let user to use it to filter the corresponding
PCTYPE packet in x722.

The new PCTYPE As bellow:
NonF Unicast IPv4, UDP
NonF Multicast IPv4, UDP
NonF IPv4, TCP, SYN, no ACK
NonF Unicast IPv6, UDP
NonF Multicast IPv6, UDP
