commit 99a6eb50ef5066e125cedb97bc0fcfcdff4f08cc Author: Antonio Quartulli antonio@open-mesh.com Date: Mon Nov 4 20:59:40 2013 +0100

batman-adv: deselect current GW on client mode switch off

When switching from gw_mode client to either off or server the current selected gateway has to be deselected. In this way when client mode is enabled again a gateway re-election is forced and a GW_ADD event is consequently sent.

The current behaviour instead is to keep the current gateway leading to no GW_ADD event when gw_mode client is selected for a second time
