Subject: [B.A.T.M.A.N.] [PATCH] batman-adv: simplify bat_ogm_receive API call
Date: Mon, 5 Dec 2011 04:01:51 +0800 [thread overview]
Message-ID: <1323028911-13495-1-git-send-email-lindner_marek@yahoo.de> (raw)
Most of the values in that call are derived from the skb, so we can hand
over the skb instead.
