Python version

3.10

Steps to Reproduce

1. Click on Add on the VDC page
2. Choose ncsu-coreswitch1 on the device drop-down
3. Click on Primary IPv6 dropdown

Expected Behavior

For context it's missing something equivalent to this logic (example for devices):

I think we can get away with just simple filters on this one as I don't think we care about NAT since this would be for management. TBH I am not sure why we care about nat_inside for regular devices either, seems unneeded to me but I am sure there is a use case somewhere (nat'd IP for a remote site or something)

Maybe it would make sense for a "available_on_device" filter similar to the one on vlans.
