I run my setup with bla enabled. Most of the entries in the global tt of my devices consist of these mac addresses. Looking through the code they come from frames which seem to be used for loop detection. Adding such MAC addresses to the local tt is prevented with the help of the batadv_bla_is_loopdetect_mac function. I wonder why adding these macs to the global tt is not prevented in a simliar way. Would it be possible to add a corresponding check to batadv_tt_global_add to prevent these macs from being added to the global tt? Or is there a specific reason why these mac addresses must occur in the global tt and which I have not understood so far?
