VM instances with macvlan doesn't coexist with docker ipvlan

Description

If I have docker containers running using ipvlan then truenas unable to start a VM with MACVLAN enabled with below error:

[EFAULT] Failed to start instance: Failed to start device "eth0": Failed adding link: Failed to run: ip link add name mac8c4ef274 link enp1s0 address 00:16:3e:76:64:83 type macvlan mode bridge: exit status 2 (RTNETLINK answers: Device or resource busy).

If I restart truenas the VM is able to to create the macvlan.
However, now docker is now unable to start containers which are using ipvlan.
Error is: Device or resource busy
I’m using dockge to manage the containers.

docker ipvlan network created using:

docker network create -d ipvlan --ipv6  --subnet=192.168.1.0/22 --gateway=192.168.1.1 --subnet=2600:xxxx:xxxx:xxxx::0/64 --gateway=2600::xxxx -o ipvlan_mode=l2 -o parent=enp1s0  myipvlan

Example compose.yaml

services:
  iperf3:
    image: mlabbe/iperf3:3.17.1-r0
    container_name: iperf3-server
    tty: true
    stdin_open: true
    mem_limit: 128M
    restart: unless-stopped
    healthcheck:
      disable: true
    networks:
      myipvlan:
        ipv4_address: 192.168.1.20
        ipv6_address: 2600:xxxx:xxxx:xxx::20
networks:
  myipvlan:
    external: true

Problem/Justification

In 25.04-RC.1 I'm unable to use VM Instances with macvlan enabled and the same time as I have docker containers running with ipvlan.

If found a post from 2016 saying the kernel doesn’t support concurrent macvlan and ipvlan on the same hardware interface.
I switch docker containers to use macvlan instead of ipvlan it looks like everything is working ok.

So fix seems to be to use MACVLAN for docker network.
