28 * State of WSS connection
29 *
30 * A device needs to connect to a neighbor in an activated WSS before data
31 * can be transmitted. The spec also distinguishes between a new connection
32 * attempt and a connection attempt after previous connection attempts. The
33 * state WLP_WSS_CONNECT_FAILED is used for this scenario. See WLP 0.99
34 * [7.2.6]
