Hi David,

our testers have discovered a regression in the current linux-3.1
code base. It increases latency of payload traffic by a factor of
4-5. Therefore we propose a patch that hopefully can be included 
before linux 3.1 final has been released. We kept it as short as 
possible to avoid introducing last minute bugs.

Once you pulled the patch you will run into a merge conflict
with net-next:
++<<<<<<< HEAD
 + orig_node = transtable_search(bat_priv, ethhdr->h_source,
 +                               ethhdr->h_dest);
 + if (is_multicast_ether_addr(ethhdr->h_dest) ||
 + (orig_node && orig_node->gw_flags)) {
+ orig_node = transtable_search(bat_priv, ethhdr->h_dest);
+ do_bcast = is_multicast_ether_addr(ethhdr->h_dest);
+ if (do_bcast || (orig_node && orig_node->gw_flags)) {
++>>>>>>> batman-adv/maint

The correct merge result would be:
orig_node = transtable_search(bat_priv, ethhdr->h_source,
do_bcast = is_multicast_ether_addr(ethhdr->h_dest);
if (do_bcast || (orig_node && orig_node->gw_flags)) {

Let me know if there is a better way to address the merge conflict.
