====================
Two of the fixes included in this patchset prevent wrong memory
access - it was triggered when removing an object from a list
after it was already free'd due to bad reference counting.
This misbehaviour existed for both the gw_node and the
orig_node_vlan object and has been fixed by Sven Eckelmann.
The last patch fixes our interface feasibility check and prevents
it from looping indefinitely when two net_device objects
reference each other via iflink index (i.e. veth pair), by
Andrew Lunn
