These modes are unknown, active, light sleep and deep sleep. Add power_mode entry to the mesh config structure to hold the user-configured default mesh power mode. This value will be used for new peer links. Add the dot11MeshAwakeWindowDuration value to the mesh config. The awake window is a duration in TU describing how long the STA will stay awake after transmitting its beacon in PS mode. Add the station parameters and flags for future userspace access.
