 Included fixes:
 - recognise and drop Bridge Loop Avoidance packets even if
   they are encapsulated in the 802.1q header multiple times.
   Forwarding them into the mesh creates issues on other
   nodes.
 - properly handle VLAN private objects in order to avoid race
   conditions upon fast VLAN deletion-addition. Such conditions
   create an unrecoverable inconsistency in the TT database of
   the nodes.

====================
pull request [net]: batman-adv 20140721

here you have two fixes that we have been testing for quite some time
(this is why they arrived a bit late in the rc cycle).

Patch 1) ensures that BLA packets get dropped and not forwarded to the
mesh even if they reach batman-adv within QinQ frames. Forwarding them
into the mesh means messing up with the TT database of other nodes which
can generate all kind of unexpected behaviours during route computation.

Patch 2) avoids a couple of race conditions triggered upon fast VLAN
deletion-addition. Such race conditions are pretty dangerous because
they not only create inconsistencies in the TT database of the nodes
in the network, but such scenario is also unrecoverable (unless
nodes are rebooted).
