Jie Wang Oct. 10, 2022, 7:25 a.m. UTC 
  Add Protocol Agnostic Flow (raw flow) support for flow subscription
in AVF.

For example, testpmd creates a flow subscription raw packet rule:
rule: eth + ipv4 src is 1.1.1.1 dst is 2.2.2.2

cmd: flow create 0 ingress pattern raw pattern spec \
00000000000000000000000008004500001400000000000000000101010102020202 \
pattern mask \
0000000000000000000000000000000000000000000000000000FFFFFFFFFFFFFFFF \
/ end actions port_representor port_id 0 / end
