So I have a machine running 22.04 ubuntu with a RJ45 ethernet card with two ports. One port has a cable plugged in, the other doesn't. The ideal situation is that I can configure both ports with an IP addr, static or assigned, carrier or no carrier. I've successfully produced this behavior on 20.04 ubuntu using the ignore-carrier option in my netplan yaml. However, this doesn't seem to translate to 22.04 for some reason. I can set a static IP or have dhcp assign an IP to the port that has a carrier, so I don't think addressing is a problem. Has anyone been able to get this feature to work on 22.04?
Here's my netplan config:
network: version: 2 renderer: networkd ethernets: enp26s0f0: dhcp4: true ignore-carrier: yes link-local: [ ipv4 ]And the resultant logs from networkd:

My backup plan is to use ifconfig to manually set the static IP for this port. This command works but it's major downside is that the assignment gets randomly lost at times and always lost on reboots.
