Nmstate patch posted to upstream: https://github.com/nmstate/nmstate/pull/2183

Also waiting NetworkManager provide applying support via bug https://bugzilla.redhat.com/show_bug.cgi?id=2156385

Comment 2 Gris Ge 2023-01-09 02:15:25 UTC

Example yaml:


```
---
interfaces:
- name: ovs0
  type: ovs-interface
  state: up
  dpdk:
    devargs: "0000:af:00.1"
    n_rxq: 100
    n-rxq-desc: 1024
    n-txq-desc: 2048
- name: br0
  type: ovs-bridge
  state: up
  bridge:
    options:
      datapath: "netdev"
    port:
    - name: ovs0
ovs-db:
  other_config:
    dpdk-init: "true"
```

Comment 3 Gris Ge 2023-01-09 02:17:56 UTC

Sorry. Please ignore above comment.

Please use this yaml once NetworkManager part is done:


```
---
interfaces:
- name: ovs0
  type: ovs-interface
  state: up
  dpdk:
    devargs: "0000:af:00.1"
    n_rxq: 100
    n_rxq_desc: 1024
    n_txq_desc: 2048
- name: br0
  type: ovs-bridge
  state: up
  bridge:
    options:
      datapath: "netdev"
    port:
    - name: ovs0
ovs-db:
  other_config:
    dpdk-init: "true"
```
