commit 8e8b91ed962f5fadb710158cbeb6b7633da4313c Author: Simon Wunderlich simon.wunderlich@s2003.tu-chemnitz.de Date: Thu Apr 25 10:37:23 2013 +0200
batctl: 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.
