batman-adv: process broadcast packets in BLA earlier
The logic in the BLA mechanism may decide to drop broadcast packets because the node may still be in the setup phase. For this reason, further broadcast processing like the early client detection mechanism must be done only after the BLA check. This patches moves the invocation to BLA before any other broadcast processing. This was introduced 30cfd02b60e1cb16f5effb0a01f826c5bb7e4c59 ("batman-adv: detect not yet announced clients") Reported-by: Glen Page <glen.page@thet.net> Signed-off-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
