Bug Description

Binary package hint: linux-image-2.6.20-15-server

- When a VLAN inferface is created from a Bridge interface, the resulting vlan interface with IP addresses etc. configured does not work.
- example /etc/network/interfaces ...

# The loopback network interface
auto lo
iface lo inet loopback

# The Bridge first ...
auto br0
iface br0 inet manual
       bridge_ports eth0 eth1
       bridge_maxwait 0
       bridge_portprio eth0 255
       bridge_pathcost eth0 65000
       bridge_stp on

# Vlans on the Bridge ...
auto vlan1
iface vlan1 inet static
        vlan-raw-device br0
        address 10.1.1.1
        netmask 255.255.255.0
        network 10.1.1.0
        broadcast 10.1.1.255
        gateway 10.1.1.254

auto vlan2
iface vlan2 inet static
        vlan-raw-device br0
        address 10.1.2.1
        netmask 255.255.255.0
        network 10.1.2.0
        broadcast 10.1.2.255

- test with vlan interfaces directly on eth0 instead of br0 performs OK.
- issue seems to be reported also on LKML and a patch has been accepted to be applied by David Miller : please see http://lkml.org/lkml/2007/4/12/289
- this construction is used for redundancy
