Subject: [PATCH/RFC 04/12] rocker: Add Open vSwitch (-like) flow support

Prototype programming of Open vSwitch (-like) flows into hardware
by implementing SWITCHDEV_OBJ_OVS_FLOW type objects in the
rocker_port_obj_{add,del} SDO, a new object type that
was added by an earlier patch in that forms part of this prototype.
