The following commit has been merged in the master branch: commit 0b94a92fc2a084ebe2d7de5cfa0f726638e311f6 Author: Marek Lindner lindner_marek@yahoo.de Date: Thu Nov 4 13:43:22 2010 +0000
batman-adv: suppress false warning when changing the mac address
Whenever the mac address of an batman interface is changed check_known_mac_addr() is called to print a warning if the newly added mac address exists an another batman interface. While looping through the batman interface list check_known_mac_addr() only compares mac addresses and does not make sure they belong to different interfaces, thus always printing a warning.
