GetAsyncReq - GetAsyncRes - SetAsync

The GetAsyncReq is just a header. The GetAsyncRes and SetAsync are identical; they start with the standard header and are followed by three sets of two masks. The three sets can be thought of as arrays of two elements. The first array consists of a two element array of PacketIn Reason codes. The second two arrays are of PortStatus Reason codes. The first element, [0], of each array indicates switch behavior for this controller if the controller's role is either: Equal, or Master. The second element, [1], indicates switch behavior for a controller with the role of Slave.
