From 7a5cc24277b57ce38eb0afa6634b71d4d5cc671e Mon Sep 17 00:00:00 2001 From: Simon Wunderlich Date: Sun, 22 Jan 2012 20:00:27 +0100 Subject: 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.
