Current behavior

Tap interfaces are created without vrf master interface:

devices:
  enp5s0:
    ipv4.address: 10.128.3.0
    ipv6.address: 2a13:dd85:310:3::0
    mtu: '1500'
    nictype: routed
    type: nic
    vrf: dc_services

tap41b45490: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

Expected behavior

Tap interfaces are created with vrf master interface:

tap41b45490: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master dc_services state UP group default qlen 1000

Steps to reproduce

1. Create vrf interface
2. Configure VM to use routed NIC with vrf

The problem was introduced in #1978 by @gwenya

https://github.com/lxc/incus/pull/1990/files#diff-f9e13fd6e2799ceb0ceccaca1006dd6429482229043bb983cb02b31430ea41d8R19-R49

For tuntap the Master parameter still exists but isn't used anymore.

For containers/veth it works.
