The transfer domain rule is able to match traffic wire/vf origin and it means two directions' underlayer resource.In customer deployments, they usually match only one direction traffic in single flow table: either from wire or from vf. Introduce one new member transfer_mode into rte_flow_template_table_attr to indicate the flow table direction property: from wire, from vf or bi-direction(default). It helps to save underlayer memory also on insertion rate, and this new field doesn't expose any matching criteira. By default, the transfer domain is to match bi-direction traffic, and no behavior changed. 1. Match wire origin only flow template_table 0 create group 0 priority 0 transfer wire_orig... 2. Match vf origin only flow template_table 0 create group 0 priority 0 transfer vf_orig...
Since wire_orig and vf_orig are just optional hints and not all PMDs are obliged to handle it, it does not impose any matching criteria. So, example above are misleading and you need to add pattern items to highlight that corresponding rules are really wire_orig or vf_orig.
