        <pre>On Fedora 21 (x86_64), when enabling systemd debug (by adding
systemd.log_level=debug to the kernel command line), rebooting 
(The systemd-networkd service is enabled, and the network service is disabled),
we see the following error in the logs (of journalctl -f), when running the
following command:

bridge vlan add dev br0 vid 1 self

...
Event source 'rtnl-receive-message' returned error, disabling: Connection reset
by peer
..

We have two config files under /etc/systemd/network:
em1.network and mynetdev.netdev:

cat em1.network
[Match]
Name=eth5

[Network]
DHCP=v4

And:
cat mynetdev.netdev
[NetDev]
Name=br0
Kind=bridge
