After the migration from isc-dhcp-client to dhcpcd my bridge
configuration

	allow-br0 eth0
	iface eth0 inet manual
	        ethernet-wol g

	auto br0
	iface br0 inet dhcp
	        bridge_ports eth0
	        bridge_stp off

does not work anymore. Both br0 and eth0 have got an IPv4 address, but
only br0 is supposed to be configured.

The above syntax appears to be incorrect. It should probably be:

-----
allow-hotplug eth0
iface eth0 inet manual

auto br0
iface br0 inet dhcp
        bridge_ports eth0
        bridge_stp off
