commit 91cff3d58a3bc2278d257fb3909f8ed3a67cb4da Author: Simon Wunderlich simon.wunderlich@s2003.tu-chemnitz.de Date: Thu Apr 25 10:37:23 2013 +0200
batman-adv: reorder packet types
Reordering the packet type numbers allows us to handle unicast packets in a general way - even if we don't know the specific packet type, we can still forward it. There was already code handling this for a couple of unicast packets, and this is the more generalized version to do that.
