Matching Interface using MAC address

New feature in nmstate 2.2.10.

Introduce two properties to base interface:

• identifier – name or mac-address, default to name
• profile-name: string

When identifier been set to mac-address, nmstate will not use interface.name for NIC matching but use the interface.mac-address, The interface.name will be used for profile-name when storing the network configuration in backend.

The profile-name will be hide if it is equal to interface name.

Example on creating MAC based profile:

---
interfaces:
  - name: wan0
    type: ethernet
    state: up
    identifier: mac-address
    mac-address: 1e:bd:23:e9:fb:94
    ipv4:
      enabled: true
      dhcp: true
    ipv6:
      enabled: true
      dhcp: true
      autoconf: true

Above profile could be delete by state:absent using name: wan0 or its real interface name.

Since nmstate version 2.2.41, you can also refer port by profile name in OVS bridge, linux bridge, VRF and bond.

Example YAML for referring bond port by MAC address:

---
interfaces:
- name: port1
  type: ethernet
  mac-address: 00:23:45:67:89:1a
  identifier: mac-address
- name: port2
  type: ethernet
  mac-address: 00:23:45:67:89:1b
  identifier: mac-address
- name: bond0
  type: bond
  state: up
  link-aggregation:
    mode: balance-rr
    ports:
      - port1
      - port2

Since nmstate version 2.2.41, you can also refer to base-interface by profile name in VLAN, VxLAN, MacSec, MacVtap, MacVlan. Example on using MAC address to identify VLAN base interface:

---
interfaces:
  - name: port1
    type: ethernet
    identifier: mac-address
    mac-address: 00:23:45:67:89:1a
  - name: vlan101
    type: vlan
    state: up
    vlan:
      base-iface: port1
      id: 101

Since nmstate version 2.2.41, you can also refer to route next-hop-interface by profile name. For example:

---
interfaces:
  - name: port1
    type: ethernet
    state: up
    mac-address: 00:23:45:67:89:1a
    identifier: mac-address
    ipv4:
      enabled: true
      address:
      - ip: 192.0.2.251
        prefix-length: 24
      dhcp: false
routes:
  config:
  - destination: 0.0.0.0/0
    next-hop-address: 192.0.2.1
    next-hop-interface: port1
