-Subject: batman-adv: Add no-rebroadcast patch
-
-Adds a patch for batman-adv which allows us to disable rebroadcasts of
-multicast "payload" frames on the incoming interface for
-specific interfaces.

-+Subject: [PATCH] batman-adv: introduce 'no_rebroadcast' option
-+MIME-Version: 1.0
-+Content-Type: text/plain; charset=UTF-8
-+Content-Transfer-Encoding: 8bit
-+
-+This patch introduces a new sysfs option named "no_rebroadcast" on
-+a per hard interface basis. It allows manually enabling a split-horizon
-+like behaviour for the layer 2 multicast payload frames, in that
-+incoming multicast payload frames on such a hard interface are only
-+being rebroadcasted on all interfaces except the incoming one instead
-+of being rebroadcasted on all interfaces.
-+
-+Such an option should only be enabled if you are certain that these
-+rebroadcasts are unnecessary. This is usually the case for instance
-+for point-to-point wifi longshots or wired links.
-+
-+This option can especially safe a significant amount of upload overhead
-+if the neighbourhood on a link is rather large, for instance in some
-+transitive, symmetric VPN configurations.
-+
-+Using this option wrongly will break your mesh network, use this option
-+wisely and at your own risk!
