[GIT net-next v2] Open vSwitch

Following patches adds recirculation and hash action to OVS.
First three patches does code restructuring which is required
for last patch.
Recirculation implementation is changed, according to comments from
David Miller, to avoid using recursive calls in OVS. It is using
queue to record recirc action and deferred recirc is executed at
the end of current actions execution.

v1-v2:
Changed subsystem name in subject to openvswitch
