[Major Hayden]

Public bug reported:

This is apparently fixed in systemd 231:

   https://lists.freedesktop.org/archives/systemd-
devel/2016-August/037385.html

When systemd tries to put a VLAN interface into a bridge on Xenial, it
fails:

# journalctl --boot -u systemd-networkd

Jan 15 09:16:46 hydrogen systemd-networkd[1903]: br-mgmt: netdev exists, using existing without changing its parameters

Here are the systemd-networkd configs I used:
