Hi,
With 2.9.x I was able to have an unconfigured physical interface and in that case, the UI shows “Subnet name: Unconfigured” and “IP Address: Unconfigured”.
Since 3.0, as soon as I switch the subnet part to “Unconfigured”, the “IP Address” state is set to “Auto assign”.
I tried to edit the interface, then unconfigure the IP address many times saving in between at each state but it keeps getting back to “Auto assign” as soon as I unconfigure the subnet part.
This should be fixed as it mislead MaaS when configuring interfaces when you don’t want a configuration done by MaaS.
