The following commit has been merged in the master branch: commit 40336a78e16b0cf77ba622ede81c405ca5f30ec4 Author: Antonio Quartulli ordex@autistici.org Date: Thu Jun 2 12:54:20 2011 +0200
batman-adv: add UNICAST_4ADDR packet type
The current unicast packet type does not contain the orig source address. This patches add a new unicast packet (called UNICAST_4ADDR) which provides two new fields: the originator source address and the subtype (the type of the data contained in the packet payload). The former is useful to identify the node which injected the packet into the network and the latter is useful to avoid creating new unicast packet types in the future: a macro defining a new subtype will be enough.
