[Bridge] [PATCH RFCv2 0/4] batman-adv: Unicasting multicast reports to querier-node only

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-nodes only. Nodes without bridges need to treat reports the same

The issue is described in detail here:


I'd also be interested in what the netdev/bridge people think about
patches #1 and #2 in particular, therefore including the according mailinglists

Cheers, Linus

 * various bugfixes (now runtime tested, too - should(tm) work)
 * added netdev+bridge mailinglists
