batman-adv: add bridge loop avoidance compile option
The define CONFIG_BATMAN_ADV_BLA switches the bridge loop avoidance on - skip it, and the bridge loop avoidance is not compiled in. This is useful if binary size should be saved or the feature is not needed. Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>
