Comment 9 for bug 1718607

Trying this with the latest beta version of Ubuntu Bionic (`apt show nplan` returns Version: 0.33), it does not seem to work: I have /etc/netplan/01-netcfg.yaml

   network:
     version: 2
     renderer: networkd
     ethernets:
       enp0s25:
         macaddress: 12:34:56:78:AB:CD
         dhcp4: true

but `ip link show enp0s25` still returns the old MAC address (after both `sudo netplan apply` and after reboot), whereas `sudo ip link set enp0s25 address 12:34:56:78:AB:CD && sudo systemctl restart systemd-networkd` works as expected.
