          Priority: medium
            Bug ID: 80031
          Assignee: systemd-bugs at lists.freedesktop.org
           Summary: systemd-networkd: master link is not brought up in
                    vlan/bridge configuration
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: lists at jameskyle.org
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

The configuration that triggers this state for me is

eth0 -> vlan100, vlan101
vlan100 -> br100
vlan101 -> br101

The eth0 link is never put into an UP state on reboot. If manually put into an
UP state with ip link set eth0 up, the other interfaces self configure and
networking works again.
