[Olsr-dev] SmartGateway: 1: no tunnel being set up to SGW server / 2: stale SGW tunnel

I digged a bit more on the netlink error, with added syslog msgs.
I see a clean install of the client tunnel. But just after it
finished, some actions are performed again, by smartgw_tunnel_monitor.
Questions:
Is it important to add route and ip to existing tunnel? Why would
route and ip disappear?
And if needed, can we eliminate the update just after install of the tunnel?
Anyway, this is not the cause of the two problems. I'll look further on those two.
