Public bug reported:

The expected hwaddresses are as follows:

4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether a0:36:9f:2d:93:80 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::a236:9fff:fe2d:9380/64 scope link

Specifically
  bond0   | True | fe80::a236:9fff:fe2d:9381/64 |       .       |  link | a0:36:9f:2d:93:81

Instead of expected a0:36:9f:2d:93:80

The generated netplan.yaml does not set macaddress on the vlans at all.

Where as the network_data.json does explicitely specifies the mac
address to be in use for those vlans:

"vlan_mac_address" : "a0:36:9f:2d:93:80"
