These are four fixes for issues which occur when using the batman-adv

The first one fixes an issue of an intermediate node snitching
multicast-to-unicast packets and either dropping it or rerouting it to
another node. Which causes lost packets on some and

For most things, yes: The querier state is kept separately for
IPv4 and IPv6. And we do have something like a "router node"
flag to signalize that a node needs all multicast traffic, which
is split into IPv4 and IPv6.

this patch relaxes the ethernet destination check for
batman-adv broadcast packets and adds the necessary capability tracking
for later compatibility checking.

Hi,
This patchset adds two improvements for the broadcast flooding
algorithm:
The first patch refactors/reorders the broadcast packet queueing.
Before a broadcast packet was always queued. Now the queueing decision
is performed on a per interface basis. Also the first broadcast is always

transmissions on wireless interfaces in the future (for instance sending
via unicast transmissions on wireless interfaces, without queueing in

The following patchset fills the next gaps in the multicast address
rules page by adding support for group-aware optimizations for
multicast addresses of scope greater than link-local. So far, only
link-local addresses were optimized as packets with routeable
addresses not only need to be
Now that we not only track the presence of multicast listeners but also
multicast routers we can safely apply group-aware multicast-to-unicast
forwarding to packets with a destination address of scope greater than
link-local as well.
