dpdk_mtu_fail.yaml

I have attached the nmstate templates (dpdk_mtu_fail.yaml). On applying the same with --no-verify, the configuration is applied and the the IP address/MTU are set. But the same yaml is applied with --verify, the configuration fails at the verification stage and its reverted.

Comment 1 Gris Ge 2023-05-04 10:38:48 UTC

The root cause here is when using `datapath: netdev` in OVS, the ovs internal interface will be based on `tun` interface. Nmstate should merge information on `tun` interface in kernel and `ovs-interface` interface in OVS daemon userspace.

Comment 2 Gris Ge 2023-05-04 10:39:45 UTC

To reproduce this problem, simply apply this state:

```yml
---
interfaces:
- name: ovs0
  type: ovs-interface
  ipv4:
    enabled: true
    address:
      - ip: 192.168.9.9
        prefix-length: 24
- name: br0
  type: ovs-bridge
  state: up
  bridge:
    options:
      datapath: "netdev"
    port:
    - name: ovs0
    - name: ovs1
ovs-db:
  other_config:
    dpdk-init: false
```
