My use-case is that when a cable is unplugged, olsrd doesn't see this.
This hurts my sgw because when the relevant interface is chosen as an 
egress interface, no new egress interface is chosen until the relevant 
HELLOs etc time-out.

By adding this, olsrd immediately sees the interface going down and sgw 
can immediately choose a new egress interface.

It makes it all more responsive.
