** Description changed:
+ [Impact]
+ Virtual devices such as VLANs, bridges and bonds may require the user to set
a specific MAC address for proper operation on networks; where the same MAC may
be used by default by the systems due to the methods used to create them.
+
+ [Test case]
+ /!\ This only works with the networkd renderer; NetworkManager does not
currently support setting a MAC on bonds and bridges.
+
+ 1) Set a MAC address for a virtual device (bond, bridge or vlan), using
+ the following syntax in netplan config:
+
+ macaddress: ##:##:##:##:##:##
+
+ 2) Validate that the device gets the MAC address applied.
+
+ [Regression potential]
+ Failure to bring up a device configured in netplan or to set the MAC should
be looked at as a possible regression. Other issues could include failure to
write the configuration for networkd or NetworkManager.

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"
