Subject: [B.A.T.M.A.N.] [PATCH] batman-adv: Avoid rounding issues for local hna timeout
Date: Sat, 19 Jun 2010 17:24:34 +0200	[thread overview]
Message-ID: <1276961074-3223-1-git-send-email-linus.luessing@web.de> (raw)

With the current default values, this patch is not critical, as
LOCAL_HNA_TIMEOUT is a multiple of 1000 anyway. However, if someone
would like to change this #define, the person could have some
unexpected rounding issues. Therefore doing the multiplication before
the division now.
