commit 5c280951b31f8ba8aab64ea5781d28de68c4bb70 Author: Simon Wunderlich simon.wunderlich@s2003.tu-chemnitz.de Date: Sat Sep 8 18:02:53 2012 +0200

batman-adv: send announcement when backbone gw is registered

To avoid loops in the startup phase until the first announcement is sent, send an announcement immediately as soon as a backbone gw is added.

This may happen due to various reasons, e.g. a packet passes the rx or tx path.
