Linus Lüssing 4c34d5fd8c batman-adv: mcast: don't send link-local multicast to mcast routers ... commit 938f2e0b57 upstream. The addition of routable multicast TX handling introduced a bug/regression for packets with a link-local multicast destination: These packets would be sent to all batman-adv nodes with a multicast router and to all batman-adv nodes with an old version without multicast router detection. This even disregards the batman-adv multicast fanout setting, which can potentially lead to an unwanted, high number of unicast transmissions or even congestion. Fixing this by avoiding to send link-local multicast packets to nodes in the multicast router list.
