[linux-next] LinuxNextTracking branch, master, updated. next-20210609

The following commit has been merged in the master branch: commit 7a68cc16b82c963c096387917ced11a27c352261 Author: Linus L��ssing <linus.luessing(a)c0d3.blue> Date: Sat May 15 17:22:08 2021 +0200 batman-adv: mcast: add MRD + routable IPv4 multicast with bridges support This adds support for routable IPv4 multicast addresses (224.0.0.0/4, excluding 224.0.0.0/24) in bridged setups. This utilizes the Multicast Router Discovery (MRD, RFC4286) support in the Linux bridge. batman-adv will now query the Linux bridge for IPv4 multicast routers, which the bridge has previously learned about via MRD. This allows us to then safely send routable IPv4 multicast packets in bridged setups to multicast listeners and multicast routers only. Before we had to flood such packets to avoid potential multicast packet loss to IPv4 multicast routers, which we were not able to detect before. With the bridge MRD integration, we are now also able to perform more fine-grained detection of IPv6 multicast routers in bridged setups: Before we were "guessing" IPv6 multicast routers by looking up multicast listeners for the link-local All Routers multicast address (ff02::2), which every IPv6 multicast router is listening to. However this would also include more nodes than necessary: For instance nodes which are just a router for unicast, but not multicast would be included, too.
