add vlan trunk support for veth
vlan trunk only support L2 only mode without any IPAM
refer ovs-cni design
https://github.com/k8snetworkplumbingwg/ovs-cni/blob/main/pkg/plugin/plugin.go
design:
origin "vlan" option will be PVID or untagged vlan for the network.
"vlanTrunk" will setup tagged vlan for veth.
entry type:
`{ "id": 100 }` will specify only tagged vlan 100
`{ "minID": 100, "maxID": 120 }` will specify tagged vlan from 100 to
120 (include 100 and 120)
vlanTrunk is a list of above entry type, so you can use this to add
tagged vlan
`[
{ "id": 100 },
{
"minID": 1000,
"maxID": 2000
}
]`
complete config will be like this
{
"cniVersion": "0.3.1",
"name": "mynet",
"type": "bridge",
"bridge": "mynet0",
"vlan": 100,
"vlanTrunk": [
{ "id": 101 },
{ "minID": 1000, "maxID": 2000 },
{ "minID": 3000, "maxID": 4000 }
],
"ipam": {}
}
