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": ""}'
[{

"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.
