Quickadd MAC address created when adding an interface can not be saves/set as primary

[Domoninic]

Deployment Type

Self-hosted

NetBox Version

V4.2.5

Python Version

3.12

Steps to Reproduce

1: Add Interface to existing Device
2: Use quickadd widget to create new primary mac address
3: set new mac address a primary
4 Save new interface

Expected Behavior

Save should work and newly create MAC should be assigned to new interface and set as primary.

Observed Behavior

Saving the new interface fails with error on field Primary MAC address "MAC address XX:XX:XX:XX:XX:XX is not assigned to this interface".
While creating the MAC address it is not possible to assign it to the new interface as that does not yet exist.
One must first save the interface then edit it and use the quick add to create the MAC as assigned to the interface and then save it.
Seems to be a chicken and egg problem.

3: set new mac address a primary

How are you doing this? There is no option to designate the MAC address as primary on the form.

Further the MAC address can't be assigned to the interface until the interface has been created.

After clicking create in the "Quick Add MAC Address" the new MAC address is automatically filled in.

I'm not sure what you're looking at. NetBox itself does not automatically populate any of the fields. Maybe your browser is auto filling the form.

But my question stands: How are you marking the MAC as primary before it is created? There is currently no option for this.

Please review your reproduction steps.
