Subject: [B.A.T.M.A.N.] [PATCH 03/19] batman-adv: compat macros/defines for local multicast group fetching
Date: Sat, 22 Jan 2011 02:21:26 +0100 [thread overview]
Message-ID: <1295659302-7171-4-git-send-email-linus.luessing@saxnet.de> (raw)
In-Reply-To: <1295659302-7171-1-git-send-email-linus.luessing@saxnet.de>
The data structures and locking mechanisms for fetching multicast mac
addresses from a net_device have changed a little between kernel
versions 2.6.21 to 2.6.35.
Therefore this commit backports two macros (netdev_mc_count(),
netdev_for_each_mc_addr()) for older kernel versions and abstracts the
way of locking and accessing the variables with own customized macros.
