Recently the autoupdater contained a case statement to distinguish
between TP-Link WDR3600 and TP-Link WDR4300. This was left over from
previous development versions of autoupdater that relied on the board
name instead of the model. It is thus no longer needed and be removed
safely.

Now that haveged starts before the config mode, there is no need to explicity
depend on it; instead it is just used when specified in the site configuration.

Disabling forwarding prevents the node from reacting to the Subnet-Router
anycast address.
