[GIT net-next v2] Open vSwitch

[Pravin B Shelar]

Following patches adds three features to OVS
1. Add fairness to upcall processing.
2. Recirculation and Hash action.
3. Enable Tunnel GSO features.
Rest of patches are bug fixes related to patches from same series.

v2 series changes first patch according to comments from Dave Miller.

[GIT net-next v2] Open vSwitch

[Pravin B Shelar]

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
