commit e917bb46159e3005e47d2d6bcd9a288ffe264160 Author: Linus Lüssing linus.luessing@c0d3.blue Date: Thu Jun 30 10:09:25 2016 +0200
batman-adv: Fix Kconfig dependencies regarding multicast optimizations
Since recently the multicast optimizations are using functions from the bridge module. If batman-adv is a kernel built-in, then these bridge functions need to be accessible immediately. Thus adding a Kconfig dependency for the multicast optimizations to depend on batman-adv being built as a module if the bridge is built as a module, too.
This fixes build errors like the following:
~~~ net/built-in.o: In function `batadv_mcast_mla_update': >> (.text+0x19b7eb): undefined reference to `br_multicast_has_querier_anywhere' net/built-in.o: In function `batadv_mcast_mla_update': >> (.text+0x19b7fa): undefined reference to `br_multicast_has_querier_adjacent' net/built-in.o: In function `batadv_mcast_mla_update': (.text+0x19b809): undefined reference to `br_multicast_has_querier_anywhere' net/built-in.o: In function `batadv_mcast_mla_update': (.text+0x19b818): undefined reference to `br_multicast_has_querier_adjacent' net/built-in.o: In function `batadv_mcast_mla_update': >> (.text+0x19b8cf): undefined reference to `br_multicast_list_adjacent' ~~~
