Thank you. It looks like the connection settings are correctly detected by NetworkManager, but for some reason it does not bring up the connection.
Could you please check the output of the following command to see how the tmfifo_net0 interface is being used?
$ nmcli dev
You could also try to "nmcli con up netplan-tmfifo_net0" to check how NetworkManager reacts to that.
