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.
