[1/2] batman-adv: fix neigh_node multiif regression in network coding
Commit Message
From: Simon Wunderlich <simon@open-mesh.com>
A previous commit for the multi interface optimization did not
change the member access for neigh_node to their respective new ifinfo
structures for the network coding implementation.
This was introduced by change 9bb33b8d88e318c4879d37d06ad28e3e018b9036
("batman-adv: split tq information in neigh_node struct")
