Subject: [B.A.T.M.A.N.] [PATCH 16/19] batman-adv: Forward multicast data in proact_tracking mode
Date: Sat, 22 Jan 2011 02:21:39 +0100	[thread overview]
Message-ID: <1295659302-7171-17-git-send-email-linus.luessing@saxnet.de> (raw)
In-Reply-To: <1295659302-7171-1-git-send-email-linus.luessing@saxnet.de>

This patch enables the forwarding of multicast data and uses the same
methods for deciding to forward via broad- or unicast(s) as the local
packet encapsulation already did.
