The following commit has been merged in the master branch: commit 9d8523931f7f5eb8900077f0da0fbe6b8ad0010b Author: Antonio Quartulli ordex@autistici.org Date: Mon Oct 17 14:25:13 2011 +0200

batman-adv: correctly set the data field in the TT_REPONSE packet

In the TT_RESPONSE packet, the number of carried entries is not correctly set. This leads to a wrong interpretation of the packet payload on the receiver side causing random entries to be added to the global translation table. Therefore the latter gets always corrupted, triggering a table recovery all the time.
