+Subject: [PATCH] maas: module: Add VLAN DHCP enable support
+
+MaaS custom py module does not support VLAN configuration.
+This should be implemented by adding a dedicated class for VLAN.
+However, we are only interested in updating an existign VLAN to
+enable DHCP on an existing IP range (set up via subnet configuration),
+so extend existing subnet handling to include basic VLAN update.
+
+NOTE: Design-wise, this is hacky, and its only purpose is to allow
+setting 'dhcp_on=True' for an existing VLAN.
+
+Example reclass model usage:
+maas:
+ region:
+ subnets:
+ 192.168.11.0/24:
+ # ...
+ vlans:
+ untagged:
+ vid: 0
+ dhcp_on: true
+ primary_rack: mas01
+
