Impossible to remove last MAC from network in UI

[Adam Collard]

It's seemingly impossible to disassociate the last MAC address from a network.

1. Create a network and associate a single MAC address
2. Navigate to http://my.maas/MAAS/networks/my-network/edit
3. Deselect the MAC (hold down Ctrl and click on the selected MAC)
4. Save Network

POST parameters are showing as:

csrfmiddlewaretoken=<redacted>
description=Auto created when creating interface eth0 on cluster beretstack
ip=10.0.7.0
name=beretstack-eth0
netmask=255.255.255.0
vlan_tag=

Note that there are no mac_address entries.

For anyone else hitting this, the workaround using CLI is a call like:
