Public bug reported:

SR-IOV accelerated Open vSwitch significantly improves the performance of OVS while maintaining its core functionality.
The idea is to leverage SR-IOV technology with OVS control plane management.

Change on the neutron side:
1. extend the OVS mechanism driver to bind direct port
2. On the agent side we will add new bridge datapath_type=hw_acc. 
3. add a check to OVS mechanism driver that in case  agent datapath_type is and hw_acc and port direct it will bind the port.

The vif change are: 
The mechanism driver will send new vif type to nova which will create hostdev interface (SR-IOV VF passthrough) and will look up the SR-IOV VF representor and plug it to the br-int

I will soon references to kernel and ovs upstream change.
