Subject: [B.A.T.M.A.N.] [PATCH 19/19] batman-adv: Make number of (re)broadcasts configurable via sysfs
Date: Sat, 22 Jan 2011 02:21:42 +0100	[thread overview]
Message-ID: <1295659302-7171-20-git-send-email-linus.luessing@saxnet.de> (raw)
In-Reply-To: <1295659302-7171-1-git-send-email-linus.luessing@saxnet.de>

Depending on the scenario, people might want to adjust the number of
(re)broadcast of data packets - usually higher values in sparse or lower
values in dense networks.
