Every time an IP address is added or removed there is a notification
generated on the "inetaddr_chain", and you seem to be properly using
this.

You have the VLAN device expansion in there as well.

Why doesn't this work?

The IP addresses cannot be added or removed from the VLAN device
until it is attached to your device.  So you should see any IP
address manipulation that occurs for VLANs stacked on top of
your device.
