From 9d8523931f7f5eb8900077f0da0fbe6b8ad0010b Mon Sep 17 00:00:00 2001 From: Antonio Quartulli <ordex@autistici.org> Date: Mon, 17 Oct 2011 14:25:13 +0200 Subject: 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.
