Doc Text:	.Support for the 802.ad `vlan-protocol` option in `nmstate` The `nmstate` API now supports creating the `linux-bridge` interfaces using the 802.ad `vlan-protocol` option. This feature enables the configuration of Service-Tag VLANs. The following example illustrates usage of this functionality in a `yaml` configuration file. ---- --- interfaces: - name: br0 type: linux-bridge state: up bridge: options: vlan-protocol: 802.1ad port: - name: eth1 vlan: mode: trunk trunk-tags: - id: 500 ----	Story Points:	---

Description Germano Veit Michel 2022-05-12 08:36:25 UTC

Description of problem:

This is a request to add the following setting to RHEL nmstate:

# nmcli con mod br1 bridge.vlan-protocol 802.1ad

Which ends up here:
/sys/class/net/br1/bridge/vlan_protocol 

It is important to enable the use of vlan stacking (802.1ad) where an S-Tag is pushed by the hypervisor and each Guest can have its own C-Tags.

To be consumed in OpenShift Virtualization by BZ2084363

Patch posted to https://github.com/nmstate/nmstate/pull/1938

Adding support of linux bridge VLAN protocol: 802.1q(default) and 802.1ad.

Example yaml:

```yaml
---
interfaces:
  - name: br0
    type: linux-bridge
    state: up
    bridge:
      options:
        vlan-protocol: 802.1ad
      port:
        - name: eth1
          vlan:
            mode: trunk
            trunk-tags:
            - id: 500
```
