From 6c519bad7b19a2c14a075b400edabaa630330123 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Fri, 27 Sep 2013 18:03:39 +0200 Subject: batman-adv: set up network coding packet handlers during module init batman-adv saves its table of packet handlers as a global state, so handlers must be set up only once (and setting them up a second time will fail). The recently-added network coding support tries to set up its handler each time a new softif is registered, which obviously fails when more that one softif is used (and in consequence, the softif creation fails). Fix this by splitting up batadv_nc_init into batadv_nc_init (which is called only once) and batadv_nc_mesh_init (which is called for each softif); in addition batadv_nc_free is renamed to batadv_nc_mesh_free to keep naming consistent.
