api: vat2 and json autogeneration for api messages
VAT2: A completely auto-generated replacement of VAT. Reads input message in JSON from stdin and outputs received messages in JSON. A VAT2 plugin is automatically built for a .api file. There no longer a need for a separate _test.c. Example: vat2 show_version {} { "_msgname": "show_version_reply", "retval": 0, "program": "vpe", "version": "21.01-rc0~411-gf6eb348a6", "build_date": "2020-11-19T09:49:25", "build_directory": "/vpp/autogen3" } vat2 sw_interface_dump '{"sw_if_index": -1, "name_filter_valid": 0, "name_filter": ""}' [{ "_msgname": "sw_interface_details", "sw_if_index": 0, "sup_sw_if_index": 0, "l2_address": "00:00:00:00:00:00", "flags": "Invalid ENUM", "type": "IF_API_TYPE_HARDWARE", "link_duplex": "LINK_DUPLEX_API_UNKNOWN", "link_speed": 0, "link_mtu": 0, "mtu": [0, 0, 0, 0], "sub_id": 0, "sub_number_of_tags": 0, "sub_outer_vlan_id": 0, "sub_inner_vlan_id": 0, "sub_if_flags": "Invalid ENUM", "vtr_op": 0, "vtr_push_dot1q": 0, "vtr_tag1": 0, "vtr_tag2": 0, "outer_tag": 0, "b_dmac": "00:00:00:00:00:00", "b_smac": "00:00:00:00:00:00", "b_vlanid": 0, "i_sid": 0, "interface_name": "local0", "interface_dev_type": "local", "tag": "" }] This is the first phase and vat2 is not integrated in packaging yet.
