From 89652331c00f43574515059ecbf262d26d885717 Mon Sep 17 00:00:00 2001 From: Simon Wunderlich Date: Wed, 13 Nov 2013 19:14:46 +0100 Subject: batman-adv: split tq information in neigh_node struct For the network wide multi interface optimization it is required to save metrics per outgoing interface in one neighbor. Therefore a new type is introduced to keep interface-specific information. This also requires some changes in access and list management. The compare and equiv_or_better API calls are changed to take the outgoing interface into consideration.
