The multicast optimizations bridge integration will require the just
implemented IGMP/MLD report handling later. Therefore bumping the
version number.

With this patch IGMP or MLD reports are only forwarded to the selected
IGMP/MLD querier as RFC4541 suggests. This is necessary to avoid
multicast packet loss in bridged scenarios later:
An IGMPv2/MLDv1 querier does not actively join the multicast group the
reports are sent to. Because of this, thi
With this patch, the IGMP and MLD message validation functions are moved
from the bridge code to the IPv4/IPv6 multicast files. Some small
refactoring was done to enhance readibility and to iron out some
differences in behaviour between the IGMP and MLD parsing code (e.g. the
skb-cloning of MLD mes
Let's use these new, neat helpers.

The last round of multicast patches send to the batman-adv mailinglist
to add support for the multicast optimizations in bridged scenarios, too,
unfortunately had one major conceptual flaw: It could lead to packet loss.
It's not sufficient to have the unicasting of reports implemented on
bridge-nod
