Comment 15 for bug 1736975

I just tested netplan 0.39 on a 18.04 VM and it does not fix the problem, the bridge is still DOWN upon creation :-(

netplan
----------------------------
network:
  version: 2
  bridges:
    br0:
      dhcp4: false
      addresses:
        - 10.10.10.254/24
      parameters:
        stp: false
        forward-delay: 0
----------------------------

which generates (netplan generate) the following files in /run/systemd/network/

10-netplan-br0.netdev
----------------------------
[NetDev]
Name=br0
Kind=bridge

[Bridge]
ForwardDelaySec=0
STP=false
----------------------------

10-netplan-br0.network
----------------------------
[Match]
Name=br0

[Network]
LinkLocalAddressing=ipv6
Address=10.10.10.254/24
ConfigureWithoutCarrier=yes
----------------------------

Now, upon "systemctl restart systemd-networkd", "ip addr" show "br0" with the correct IP address but still "DOWN"!

----------------------------
4: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
[...]
----------------------------

The problem is not solved!
