In some case, we don't care the enc_src_ip and enc_dst_ip, and if we don't match the field enc_src_ip and enc_dst_ip, we can use fewer flows in hardware when revice the tunnel packets. For example, the tunnel packets may be sent from different hosts, we must offload one rule for each host.

If we support flows which only match the enc_key_id and enc_dst_port, a flow can process the packets sent to VM which (mac 00:11:22:33:44:00).
