Support flow subscribption create/destroy/validation flow
rule for AVF.
For examples:
testpmd> flow create 0 ingress pattern eth / ipv4 / udp src is 11
/ end actions represented_port port_id 1 / end
testpmd> flow validate 1 ingress pattern eth / ipv4 / tcp src is 22
/ end actions represented_port port_id 1 / end
testpmd> flow destroy 1 rule 0
VF subscribes to a rule, which means the packets will be sent to VF
instead of PF, and only VF will receive the packets.
It is allowed multiple VF subscribe to same rule, the packets will
be replicated and received by each VF.
PF will destroy all subscriptions during VF reset.
