Public bug reported: The 8021q kernel module was moved from the linux-modules package to the linux-modules-extras package for the Raspberry Pi. This means that vlans cannot be configured if the linux-modules-extras package is not installed. The release notes mention that some modules have been moved and to install the linux-modules-extra package if your application doesn't work. This would be adequate warning except for one issue. Systemd-networkd will fail to configure an ip address for the raspberry pi's ethernet interface when the vlans cannot be configured leaving headless systems inaccessible. I suffered this exact scenario upon upgrading since my netplan file included vlans assigned to the Pi's ethernet interface. I would recommend either updating the release notes to specifically call out this scenario or move the 8021q module back to the linux-modules package.
