Using OVS internal interfaces instead of veth ?

[champtar]

Has anyone attempted to use OVS internal interfaces instead of veth ?
It was mentioned a long time ago by @phoracek in #2 (comment)_ but can't find anything about why it was never done (maybe some hard blocker)

BTW the documentation is misleading:

ovs-cni/docs/cni-plugin.md

Line 60 in 8a4f334

* `interface_type` (string, optional): type of the interface belongs to ports. if value is "", ovs will use default interface of type 'internal'

In my testing I have

# ovs-vsctl show
ffe87f74-4b6f-42f6-87b6-25504ab94ce3
    Bridge k8s-ovs
        Port k8s-ovs
            Interface k8s-ovs
                type: internal
        Port veth97d92a70
            Interface veth97d92a70
    ovs_version: "3.2.2"
